Let's divide 90311010 by 657
Our goal is to divide 90311010 by 657.

Step 1:
The number 657 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 657

Let's proceed to step 2:
90 divided by 657 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 657

Step 3:
657 can be fit into 903 1 times, resulting in a remainder of 246.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 657 from 903 to get 246.
Fetch the next digit (1) from the dividend, attach it to 246 and continue: 2461 / 657

Moving on to step 4:
When dividing 2461 by 657, we get 3 with a remainder of 490.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1971 away from 2461, we end up with 490.
Include the next digit (1) from the dividend after 490, then repeat: 4901 / 657

On to step 5:
4901 divided by 657 is 7 with a remainder of 302.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 4599 from 4901 to get 302.
Fetch the next digit (0) from the dividend, attach it to 302 and continue: 3020 / 657

On to step 6:
If we divide 3020 by 657, we get 4 and a remainder of 392.
Put 4 as the next digit of the answer. 
Result so far: 1374.0
Subtracting 2628 from 3020 leaves us with 392.
Take the next digit (1) from the dividend and append it to 392, then repeat: 3921 / 657

Let's proceed to step 7:
657 goes into 3921 5 times with a remainder of 636.
Write down 5 as next digit of the result. 
Result so far: 13745.0
If we take 3285 away from 3921, we end up with 636.
Include the next digit (0) from the dividend after 636, then repeat: 6360 / 657

Moving on to step 8:
657 goes into 6360 9 times with a remainder of 447.
The number 9 becomes the next digit in our result. 
Result so far: 137459.0
If we subtract 5913 from 6360, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 9:
4470 divided by 657 is 6 with a remainder of 528.
Put 6 as the next digit of the answer. 
Result so far: 137459.6
If we subtract 3942 from 4470, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 10:
The number 657 fits into 5280 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 137459.68
If we take 5256 away from 5280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 657, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 137459.68
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
The number 657 fits into 2400 3 times, leaving a remainder of 429.
Write down 3 as next digit of the result. 
Result so far: 137459.6803
If we take 1971 away from 2400, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 13:
The number 657 fits into 4290 6 times, leaving a remainder of 348.
The number 6 becomes the next digit in our result. 
Result so far: 137459.68036
If we take 3942 away from 4290, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 14:
657 can be fit into 3480 5 times, resulting in a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 137459.680365
If we subtract 3285 from 3480, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 15:
If we divide 1950 by 657, we get 2 and a remainder of 636.
Write down 2 as next digit of the result. 
Result so far: 137459.6803652
If we subtract 1314 from 1950, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 16:
6360 divided by 657 is 9 with a remainder of 447.
Put 9 as the next digit of the answer. 
Result so far: 137459.68036529
If we take 5913 away from 6360, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

After the division, we end up with 137459.68036529 and a remainder of 4.47e-07.
