91961027 divided by 661 
Our goal is to divide 91961027 by 661.

Going ahead to step 1:
When dividing 9 by 661, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 661

On to step 2:
When dividing 91 by 661, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Fetch the next digit (9) from the dividend, attach it to 91 and continue: 919 / 661

Let's proceed to step 3:
919 divided by 661 is 1 with a remainder of 258.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 661 away from 919, we end up with 258.
Bring next digit (6) of the dividend behind the 258 and repeat the process: 2586 / 661

Advancing to step 4:
When dividing 2586 by 661, we get 3 with a remainder of 603.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1983 from 2586, we get 603.
Take the next digit (1) from the dividend and append it to 603, then repeat: 6031 / 661

Moving on to step 5:
If we divide 6031 by 661, we get 9 and a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Deduct 5949 from 6031 and we're left with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 661

Let's proceed to step 6:
When dividing 820 by 661, we get 1 with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
Subtracting 661 from 820 leaves us with 159.
Append the next digit (2) from the dividend to 159 and continue with: 1592 / 661

Step 7:
661 can be fit into 1592 2 times, resulting in a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 13912.0
If we take 1322 away from 1592, we end up with 270.
Append the next digit (7) from the dividend to 270 and continue with: 2707 / 661

Moving on to step 8:
2707 divided by 661 is 4 with a remainder of 63.
The next digit of our result is 4. 
Result so far: 139124.0
Subtracting 2644 from 2707 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
661 can be fit into 630 0 times, resulting in a remainder of 630.
The next digit of our result is 0. 
Result so far: 139124.0
If we take 0 away from 630, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 10:
The number 661 fits into 6300 9 times, leaving a remainder of 351.
Put 9 as the next digit of the answer. 
Result so far: 139124.09
The remainder is 351 after subtracting 5949 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 11:
661 goes into 3510 5 times with a remainder of 205.
The next digit of our result is 5. 
Result so far: 139124.095
If we take 3305 away from 3510, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 12:
661 can be fit into 2050 3 times, resulting in a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 139124.0953
If we take 1983 away from 2050, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
661 goes into 670 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 139124.09531
Deduct 661 from 670 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
661 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 139124.09531
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
661 goes into 900 1 times with a remainder of 239.
The next digit of our result is 1. 
Result so far: 139124.0953101
Deduct 661 from 900 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 16:
When dividing 2390 by 661, we get 3 with a remainder of 407.
Put 3 as the next digit of the answer. 
Result so far: 139124.09531013
If we take 1983 away from 2390, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

The quotient of the division is 139124.09531013, and the remainder is 4.07e-07.
