We're dividing 77285660 by 891 
We want to divide 77285660 by 891.

Moving on to step 1:
891 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 891

Going ahead to step 2:
891 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 891

On to step 3:
The number 891 fits into 772 0 times, leaving a remainder of 772.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 772, we end up with 772.
Include the next digit (8) from the dividend after 772, then repeat: 7728 / 891

Moving on to step 4:
7728 divided by 891 is 8 with a remainder of 600.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7128 from 7728 leaves us with 600.
Fetch the next digit (5) from the dividend, attach it to 600 and continue: 6005 / 891

Going ahead to step 5:
If we divide 6005 by 891, we get 6 and a remainder of 659.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 5346 from 6005 to get 659.
Bring next digit (6) of the dividend behind the 659 and repeat the process: 6596 / 891

Advancing to step 6:
When dividing 6596 by 891, we get 7 with a remainder of 359.
Put 7 as the next digit of the answer. 
Result so far: 867.0
If we take 6237 away from 6596, we end up with 359.
Fetch the next digit (6) from the dividend, attach it to 359 and continue: 3596 / 891

Let's proceed to step 7:
891 goes into 3596 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 8674.0
The remainder is 32 after subtracting 3564 from 3596.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 891

Going ahead to step 8:
If we divide 320 by 891, we get 0 and a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 86740.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
891 can be fit into 3200 3 times, resulting in a remainder of 527.
Use 3 as the next digit of our solution. 
Result so far: 86740.3
Subtracting 2673 from 3200 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 10:
When dividing 5270 by 891, we get 5 with a remainder of 815.
The next digit of our result is 5. 
Result so far: 86740.35
If we subtract 4455 from 5270, we get 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Step 11:
When dividing 8150 by 891, we get 9 with a remainder of 131.
Write down 9 as next digit of the result. 
Result so far: 86740.359
Subtracting 8019 from 8150 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 12:
If we divide 1310 by 891, we get 1 and a remainder of 419.
Record the quotient 1 as the next digit in the result. 
Result so far: 86740.3591
Subtract 891 from 1310 to get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 13:
891 can be fit into 4190 4 times, resulting in a remainder of 626.
The next digit of our result is 4. 
Result so far: 86740.35914
Subtracting 3564 from 4190 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 14:
891 goes into 6260 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 86740.359147
Subtract 6237 from 6260 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 15:
If we divide 230 by 891, we get 0 and a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 86740.359147
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 16:
When dividing 2300 by 891, we get 2 with a remainder of 518.
Write down 2 as next digit of the result. 
Result so far: 86740.35914702
If we subtract 1782 from 2300, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

The final outcome is 86740.35914702, with a leftover of 5.18e-07.
