We look at the division of 86664021 by 481 
We want to divide 86664021 by 481.

Moving on to step 1:
When dividing 8 by 481, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 481

Going ahead to step 2:
The number 481 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 481

Going ahead to step 3:
If we divide 866 by 481, we get 1 and a remainder of 385.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 385 after subtracting 481 from 866.
Take the next digit (6) from the dividend and append it to 385, then repeat: 3856 / 481

On to step 4:
3856 divided by 481 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 3848 from 3856 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 481

Advancing to step 5:
If we divide 84 by 481, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we subtract 0 from 84, we get 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 481

Advancing to step 6:
840 divided by 481 is 1 with a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 1801.0
Subtracting 481 from 840 leaves us with 359.
Include the next digit (2) from the dividend after 359, then repeat: 3592 / 481

Going ahead to step 7:
When dividing 3592 by 481, we get 7 with a remainder of 225.
Put 7 as the next digit of the answer. 
Result so far: 18017.0
Subtract 3367 from 3592 to get 225.
Bring next digit (1) of the dividend behind the 225 and repeat the process: 2251 / 481

On to step 8:
The number 481 fits into 2251 4 times, leaving a remainder of 327.
The number 4 becomes the next digit in our result. 
Result so far: 180174.0
Deduct 1924 from 2251 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
If we divide 3270 by 481, we get 6 and a remainder of 384.
Use 6 as the next digit of our solution. 
Result so far: 180174.6
If we take 2886 away from 3270, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
481 goes into 3840 7 times with a remainder of 473.
Write down 7 as next digit of the result. 
Result so far: 180174.67
If we take 3367 away from 3840, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 11:
481 can be fit into 4730 9 times, resulting in a remainder of 401.
Record the quotient 9 as the next digit in the result. 
Result so far: 180174.679
Subtracting 4329 from 4730 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Advancing to step 12:
If we divide 4010 by 481, we get 8 and a remainder of 162.
Record the quotient 8 as the next digit in the result. 
Result so far: 180174.6798
If we take 3848 away from 4010, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 13:
The number 481 fits into 1620 3 times, leaving a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 180174.67983
Subtracting 1443 from 1620 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 14:
1770 divided by 481 is 3 with a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 180174.679833
The remainder is 327 after subtracting 1443 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The final outcome is 180174.679833, with a leftover of 3.27e-05.
