We're dividing 977751 by 91 
We want to figure out the number of times 977751 can be divided by 91.

On to step 1:
If we divide 9 by 91, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 91

Moving on to step 2:
The number 91 fits into 97 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 91 from 97 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 91

Step 3:
When dividing 67 by 91, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 67 and we're left with 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 91

Let's proceed to step 4:
91 goes into 677 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 40 after subtracting 637 from 677.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 91

Advancing to step 5:
The number 91 fits into 405 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 1074.0
Deduct 364 from 405 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 91

Going ahead to step 6:
If we divide 411 by 91, we get 4 and a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 10744.0
Subtracting 364 from 411 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
91 goes into 470 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10744.5
The remainder is 15 after subtracting 455 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
150 divided by 91 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 10744.51
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
If we divide 590 by 91, we get 6 and a remainder of 44.
The next digit of our result is 6. 
Result so far: 10744.516
Deduct 546 from 590 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
91 goes into 440 4 times with a remainder of 76.
The next digit of our result is 4. 
Result so far: 10744.5164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
When dividing 760 by 91, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10744.51648
Subtracting 728 from 760 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
91 goes into 320 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 10744.516483
Deduct 273 from 320 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10744.5164835
The remainder is 15 after subtracting 455 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
91 can be fit into 150 1 times, resulting in a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 10744.51648351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 10744.51648351, with a leftover of 5.9e-08.
