80101644 divided by 657 
Let's see how many times 657 fits into 80101644.

On to step 1:
When dividing 8 by 657, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 657

Advancing to step 2:
When dividing 80 by 657, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 657

Advancing to step 3:
When dividing 801 by 657, we get 1 with a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 657 from 801 to get 144.
Append the next digit (0) from the dividend to 144 and continue with: 1440 / 657

On to step 4:
The number 657 fits into 1440 2 times, leaving a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1314 from 1440 to get 126.
Append the next digit (1) from the dividend to 126 and continue with: 1261 / 657

Moving on to step 5:
657 goes into 1261 1 times with a remainder of 604.
The next digit of our result is 1. 
Result so far: 121.0
If we take 657 away from 1261, we end up with 604.
Bring next digit (6) of the dividend behind the 604 and repeat the process: 6046 / 657

Step 6:
If we divide 6046 by 657, we get 9 and a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 1219.0
Subtract 5913 from 6046 to get 133.
Include the next digit (4) from the dividend after 133, then repeat: 1334 / 657

Moving on to step 7:
657 goes into 1334 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 12192.0
Deduct 1314 from 1334 and we're left with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 657

Going ahead to step 8:
204 divided by 657 is 0 with a remainder of 204.
The next digit of our result is 0. 
Result so far: 121920.0
If we take 0 away from 204, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 9:
657 goes into 2040 3 times with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 121920.3
If we take 1971 away from 2040, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 10:
If we divide 690 by 657, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 121920.31
Deduct 657 from 690 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
657 goes into 330 0 times with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 121920.31
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 12:
657 can be fit into 3300 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 121920.3105
The remainder is 15 after subtracting 3285 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
657 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 121920.3105
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 14:
657 can be fit into 1500 2 times, resulting in a remainder of 186.
Put 2 as the next digit of the answer. 
Result so far: 121920.310502
If we take 1314 away from 1500, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 15:
657 goes into 1860 2 times with a remainder of 546.
Record the quotient 2 as the next digit in the result. 
Result so far: 121920.3105022
If we take 1314 away from 1860, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

After the division, we end up with 121920.3105022 and a remainder of 5.46e-06.
