91735291 divided by 661 
We want to divide 91735291 by 661.

On to step 1:
If we divide 9 by 661, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 661

Let's proceed to step 2:
When dividing 91 by 661, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 661

Step 3:
The number 661 fits into 917 1 times, leaving a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 661 from 917 and we're left with 256.
Bring next digit (3) of the dividend behind the 256 and repeat the process: 2563 / 661

On to step 4:
661 can be fit into 2563 3 times, resulting in a remainder of 580.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1983 away from 2563, we end up with 580.
Append the next digit (5) from the dividend to 580 and continue with: 5805 / 661

Advancing to step 5:
661 can be fit into 5805 8 times, resulting in a remainder of 517.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtracting 5288 from 5805 leaves us with 517.
Take the next digit (2) from the dividend and append it to 517, then repeat: 5172 / 661

Step 6:
5172 divided by 661 is 7 with a remainder of 545.
Record the quotient 7 as the next digit in the result. 
Result so far: 1387.0
The remainder is 545 after subtracting 4627 from 5172.
Grab the next digit (9) from the dividend, add it to 545, then carry on: 5459 / 661

On to step 7:
661 goes into 5459 8 times with a remainder of 171.
Write down 8 as next digit of the result. 
Result so far: 13878.0
The remainder is 171 after subtracting 5288 from 5459.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 661

Step 8:
When dividing 1711 by 661, we get 2 with a remainder of 389.
Put 2 as the next digit of the answer. 
Result so far: 138782.0
If we take 1322 away from 1711, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 9:
661 can be fit into 3890 5 times, resulting in a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 138782.5
Subtracting 3305 from 3890 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 10:
5850 divided by 661 is 8 with a remainder of 562.
The next digit of our result is 8. 
Result so far: 138782.58
The remainder is 562 after subtracting 5288 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 11:
5620 divided by 661 is 8 with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 138782.588
Subtracting 5288 from 5620 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final result is 138782.588 with a remainder of 0.0332.
