Let's divide 81631693 by 657
We're looking to find how many times 657 goes into 81631693.

Step 1:
The number 657 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 657

On to step 2:
657 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 657

Moving on to step 3:
When dividing 816 by 657, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 657 away from 816, we end up with 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 657

Advancing to step 4:
The number 657 fits into 1593 2 times, leaving a remainder of 279.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1314 away from 1593, we end up with 279.
Include the next digit (1) from the dividend after 279, then repeat: 2791 / 657

Step 5:
When dividing 2791 by 657, we get 4 with a remainder of 163.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 2628 from 2791 leaves us with 163.
Include the next digit (6) from the dividend after 163, then repeat: 1636 / 657

Advancing to step 6:
657 can be fit into 1636 2 times, resulting in a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 1242.0
Subtracting 1314 from 1636 leaves us with 322.
Grab the next digit (9) from the dividend, add it to 322, then carry on: 3229 / 657

Step 7:
If we divide 3229 by 657, we get 4 and a remainder of 601.
Put 4 as the next digit of the answer. 
Result so far: 12424.0
If we take 2628 away from 3229, we end up with 601.
Bring next digit (3) of the dividend behind the 601 and repeat the process: 6013 / 657

Going ahead to step 8:
The number 657 fits into 6013 9 times, leaving a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 124249.0
If we subtract 5913 from 6013, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
657 can be fit into 1000 1 times, resulting in a remainder of 343.
Put 1 as the next digit of the answer. 
Result so far: 124249.1
Subtracting 657 from 1000 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 10:
3430 divided by 657 is 5 with a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 124249.15
Deduct 3285 from 3430 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
657 goes into 1450 2 times with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 124249.152
Subtracting 1314 from 1450 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
657 goes into 1360 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 124249.1522
Deduct 1314 from 1360 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 124249.1522 and a remainder of 0.00046.
