Let's divide 90731666 by 657
Our goal is to divide 90731666 by 657.

Let's proceed to step 1:
If we divide 9 by 657, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 657

Step 2:
90 divided by 657 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 657

Advancing to step 3:
If we divide 907 by 657, we get 1 and a remainder of 250.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 657 from 907, we get 250.
Grab the next digit (3) from the dividend, add it to 250, then carry on: 2503 / 657

Going ahead to step 4:
If we divide 2503 by 657, we get 3 and a remainder of 532.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1971 from 2503 and we're left with 532.
Include the next digit (1) from the dividend after 532, then repeat: 5321 / 657

Let's proceed to step 5:
657 can be fit into 5321 8 times, resulting in a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 138.0
The remainder is 65 after subtracting 5256 from 5321.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 657

Step 6:
If we divide 656 by 657, we get 0 and a remainder of 656.
Use 0 as the next digit of our solution. 
Result so far: 1380.0
Subtracting 0 from 656 leaves us with 656.
Fetch the next digit (6) from the dividend, attach it to 656 and continue: 6566 / 657

Step 7:
If we divide 6566 by 657, we get 9 and a remainder of 653.
The number 9 becomes the next digit in our result. 
Result so far: 13809.0
Deduct 5913 from 6566 and we're left with 653.
Append the next digit (6) from the dividend to 653 and continue with: 6536 / 657

Going ahead to step 8:
When dividing 6536 by 657, we get 9 with a remainder of 623.
The next digit of our result is 9. 
Result so far: 138099.0
Subtracting 5913 from 6536 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 9:
6230 divided by 657 is 9 with a remainder of 317.
The next digit of our result is 9. 
Result so far: 138099.9
The remainder is 317 after subtracting 5913 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 10:
657 can be fit into 3170 4 times, resulting in a remainder of 542.
Put 4 as the next digit of the answer. 
Result so far: 138099.94
Subtract 2628 from 3170 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 11:
The number 657 fits into 5420 8 times, leaving a remainder of 164.
Use 8 as the next digit of our solution. 
Result so far: 138099.948
If we subtract 5256 from 5420, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 12:
If we divide 1640 by 657, we get 2 and a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 138099.9482
If we take 1314 away from 1640, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
657 goes into 3260 4 times with a remainder of 632.
The next digit of our result is 4. 
Result so far: 138099.94824
The remainder is 632 after subtracting 2628 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 14:
657 can be fit into 6320 9 times, resulting in a remainder of 407.
The next digit of our result is 9. 
Result so far: 138099.948249
Subtract 5913 from 6320 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 15:
The number 657 fits into 4070 6 times, leaving a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 138099.9482496
Subtracting 3942 from 4070 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 16:
If we divide 1280 by 657, we get 1 and a remainder of 623.
Put 1 as the next digit of the answer. 
Result so far: 138099.94824961
The remainder is 623 after subtracting 657 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

In conclusion, the division gives 138099.94824961 with a balance of 6.23e-07.
