Let's divide 660861 by 91
Our goal is to divide 660861 by 91.

Step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Step 2:
When dividing 66 by 91, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 91

Going ahead to step 3:
91 goes into 660 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 637 from 660, we get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 91

On to step 4:
91 can be fit into 238 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 182 from 238, we get 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 91

Let's proceed to step 5:
The number 91 fits into 566 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 726.0
Subtract 546 from 566 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 91

Moving on to step 6:
When dividing 201 by 91, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 7262.0
Subtract 182 from 201 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
91 can be fit into 190 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7262.2
Subtract 182 from 190 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
91 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 7262.2
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
800 divided by 91 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 7262.208
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
91 goes into 720 7 times with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 7262.2087
Subtracting 637 from 720 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 11:
830 divided by 91 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 7262.20879
The remainder is 11 after subtracting 819 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
91 goes into 110 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 7262.208791
The remainder is 19 after subtracting 91 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
190 divided by 91 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7262.2087912
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 91, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 7262.2087912
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 7262.2087912, and the remainder is 8e-08.
