We look at the division of 78735578 by 891 
Let's see how many times 891 fits into 78735578.

Step 1:
The number 891 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 891

Advancing to step 2:
891 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 891

Let's proceed to step 3:
787 divided by 891 is 0 with a remainder of 787.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 787 and we're left with 787.
Take the next digit (3) from the dividend and append it to 787, then repeat: 7873 / 891

Moving on to step 4:
The number 891 fits into 7873 8 times, leaving a remainder of 745.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 745 after subtracting 7128 from 7873.
Grab the next digit (5) from the dividend, add it to 745, then carry on: 7455 / 891

Going ahead to step 5:
891 goes into 7455 8 times with a remainder of 327.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 7128 away from 7455, we end up with 327.
Fetch the next digit (5) from the dividend, attach it to 327 and continue: 3275 / 891

Step 6:
When dividing 3275 by 891, we get 3 with a remainder of 602.
Put 3 as the next digit of the answer. 
Result so far: 883.0
Subtract 2673 from 3275 to get 602.
Bring next digit (7) of the dividend behind the 602 and repeat the process: 6027 / 891

Step 7:
When dividing 6027 by 891, we get 6 with a remainder of 681.
The number 6 becomes the next digit in our result. 
Result so far: 8836.0
If we subtract 5346 from 6027, we get 681.
Bring next digit (8) of the dividend behind the 681 and repeat the process: 6818 / 891

On to step 8:
891 can be fit into 6818 7 times, resulting in a remainder of 581.
Record the quotient 7 as the next digit in the result. 
Result so far: 88367.0
If we subtract 6237 from 6818, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Step 9:
The number 891 fits into 5810 6 times, leaving a remainder of 464.
Write down 6 as next digit of the result. 
Result so far: 88367.6
The remainder is 464 after subtracting 5346 from 5810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 10:
891 goes into 4640 5 times with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 88367.65
Subtract 4455 from 4640 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
When dividing 1850 by 891, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 88367.652
The remainder is 68 after subtracting 1782 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
The number 891 fits into 680 0 times, leaving a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 88367.652
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 13:
891 can be fit into 6800 7 times, resulting in a remainder of 563.
The next digit of our result is 7. 
Result so far: 88367.65207
Deduct 6237 from 6800 and we're left with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 14:
891 goes into 5630 6 times with a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 88367.652076
Subtract 5346 from 5630 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 15:
2840 divided by 891 is 3 with a remainder of 167.
The next digit of our result is 3. 
Result so far: 88367.6520763
If we take 2673 away from 2840, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 16:
If we divide 1670 by 891, we get 1 and a remainder of 779.
The next digit of our result is 1. 
Result so far: 88367.65207631
The remainder is 779 after subtracting 891 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

The final outcome is 88367.65207631, with a leftover of 7.79e-07.
