We're dividing 66306977 by 353 
Our goal is to divide 66306977 by 353.

On to step 1:
353 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 353

On to step 2:
66 divided by 353 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 353

Advancing to step 3:
353 can be fit into 663 1 times, resulting in a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 353 from 663, we get 310.
Grab the next digit (0) from the dividend, add it to 310, then carry on: 3100 / 353

Going ahead to step 4:
When dividing 3100 by 353, we get 8 with a remainder of 276.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 2824 away from 3100, we end up with 276.
Append the next digit (6) from the dividend to 276 and continue with: 2766 / 353

Let's proceed to step 5:
If we divide 2766 by 353, we get 7 and a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtracting 2471 from 2766 leaves us with 295.
Fetch the next digit (9) from the dividend, attach it to 295 and continue: 2959 / 353

Let's proceed to step 6:
If we divide 2959 by 353, we get 8 and a remainder of 135.
Record the quotient 8 as the next digit in the result. 
Result so far: 1878.0
Deduct 2824 from 2959 and we're left with 135.
Append the next digit (7) from the dividend to 135 and continue with: 1357 / 353

Advancing to step 7:
When dividing 1357 by 353, we get 3 with a remainder of 298.
Write down 3 as next digit of the result. 
Result so far: 18783.0
Subtract 1059 from 1357 to get 298.
Take the next digit (7) from the dividend and append it to 298, then repeat: 2987 / 353

On to step 8:
353 goes into 2987 8 times with a remainder of 163.
The number 8 becomes the next digit in our result. 
Result so far: 187838.0
The remainder is 163 after subtracting 2824 from 2987.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 9:
353 goes into 1630 4 times with a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 187838.4
The remainder is 218 after subtracting 1412 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 10:
If we divide 2180 by 353, we get 6 and a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 187838.46
Subtract 2118 from 2180 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
353 goes into 620 1 times with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 187838.461
If we take 353 away from 620, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 12:
If we divide 2670 by 353, we get 7 and a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 187838.4617
If we take 2471 away from 2670, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 13:
The number 353 fits into 1990 5 times, leaving a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 187838.46175
If we take 1765 away from 1990, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 14:
When dividing 2250 by 353, we get 6 with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 187838.461756
Subtract 2118 from 2250 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
353 goes into 1320 3 times with a remainder of 261.
Use 3 as the next digit of our solution. 
Result so far: 187838.4617563
If we take 1059 away from 1320, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 16:
When dividing 2610 by 353, we get 7 with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 187838.46175637
Deduct 2471 from 2610 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The final outcome is 187838.46175637, with a leftover of 1.39e-07.
