We're dividing 66071092 by 475 
We want to divide 66071092 by 475.

On to step 1:
475 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 475

Going ahead to step 2:
If we divide 66 by 475, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 475

Advancing to step 3:
If we divide 660 by 475, we get 1 and a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 475 away from 660, we end up with 185.
Fetch the next digit (7) from the dividend, attach it to 185 and continue: 1857 / 475

On to step 4:
The number 475 fits into 1857 3 times, leaving a remainder of 432.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 432 after subtracting 1425 from 1857.
Grab the next digit (1) from the dividend, add it to 432, then carry on: 4321 / 475

Step 5:
When dividing 4321 by 475, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 4275 from 4321, we get 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 475

Moving on to step 6:
The number 475 fits into 460 0 times, leaving a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 1390.0
Deduct 0 from 460 and we're left with 460.
Bring next digit (9) of the dividend behind the 460 and repeat the process: 4609 / 475

Let's proceed to step 7:
The number 475 fits into 4609 9 times, leaving a remainder of 334.
Record the quotient 9 as the next digit in the result. 
Result so far: 13909.0
Subtract 4275 from 4609 to get 334.
Take the next digit (2) from the dividend and append it to 334, then repeat: 3342 / 475

Step 8:
475 goes into 3342 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 139097.0
The remainder is 17 after subtracting 3325 from 3342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
The number 475 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 139097.0
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
1700 divided by 475 is 3 with a remainder of 275.
The number 3 becomes the next digit in our result. 
Result so far: 139097.03
The remainder is 275 after subtracting 1425 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 11:
The number 475 fits into 2750 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 139097.035
The remainder is 375 after subtracting 2375 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 12:
The number 475 fits into 3750 7 times, leaving a remainder of 425.
Record the quotient 7 as the next digit in the result. 
Result so far: 139097.0357
The remainder is 425 after subtracting 3325 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 13:
The number 475 fits into 4250 8 times, leaving a remainder of 450.
Use 8 as the next digit of our solution. 
Result so far: 139097.03578
Deduct 3800 from 4250 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 14:
4500 divided by 475 is 9 with a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 139097.035789
The remainder is 225 after subtracting 4275 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 15:
The number 475 fits into 2250 4 times, leaving a remainder of 350.
The next digit of our result is 4. 
Result so far: 139097.0357894
Subtracting 1900 from 2250 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 16:
475 can be fit into 3500 7 times, resulting in a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 139097.03578947
The remainder is 175 after subtracting 3325 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

After the division, we end up with 139097.03578947 and a remainder of 1.75e-07.
