We look at the division of 71129878 by 891 
Let's see how many times 891 fits into 71129878.

Step 1:
The number 891 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 891

Going ahead to step 2:
891 goes into 71 0 times with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 891

Moving on to step 3:
711 divided by 891 is 0 with a remainder of 711.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 711 to get 711.
Bring next digit (2) of the dividend behind the 711 and repeat the process: 7112 / 891

On to step 4:
891 can be fit into 7112 7 times, resulting in a remainder of 875.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6237 away from 7112, we end up with 875.
Bring next digit (9) of the dividend behind the 875 and repeat the process: 8759 / 891

Moving on to step 5:
8759 divided by 891 is 9 with a remainder of 740.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 8019 from 8759 leaves us with 740.
Fetch the next digit (8) from the dividend, attach it to 740 and continue: 7408 / 891

Moving on to step 6:
891 goes into 7408 8 times with a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 798.0
Subtracting 7128 from 7408 leaves us with 280.
Bring next digit (7) of the dividend behind the 280 and repeat the process: 2807 / 891

Step 7:
2807 divided by 891 is 3 with a remainder of 134.
Put 3 as the next digit of the answer. 
Result so far: 7983.0
Deduct 2673 from 2807 and we're left with 134.
Append the next digit (8) from the dividend to 134 and continue with: 1348 / 891

Let's proceed to step 8:
891 goes into 1348 1 times with a remainder of 457.
Put 1 as the next digit of the answer. 
Result so far: 79831.0
The remainder is 457 after subtracting 891 from 1348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 9:
The number 891 fits into 4570 5 times, leaving a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 79831.5
Deduct 4455 from 4570 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 10:
891 goes into 1150 1 times with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 79831.51
Subtracting 891 from 1150 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 11:
891 can be fit into 2590 2 times, resulting in a remainder of 808.
Record the quotient 2 as the next digit in the result. 
Result so far: 79831.512
If we subtract 1782 from 2590, we get 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Advancing to step 12:
891 can be fit into 8080 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 79831.5129
Subtracting 8019 from 8080 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
The number 891 fits into 610 0 times, leaving a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 79831.5129
Deduct 0 from 610 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 14:
The number 891 fits into 6100 6 times, leaving a remainder of 754.
The number 6 becomes the next digit in our result. 
Result so far: 79831.512906
The remainder is 754 after subtracting 5346 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Advancing to step 15:
If we divide 7540 by 891, we get 8 and a remainder of 412.
Write down 8 as next digit of the result. 
Result so far: 79831.5129068
Deduct 7128 from 7540 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 16:
When dividing 4120 by 891, we get 4 with a remainder of 556.
The number 4 becomes the next digit in our result. 
Result so far: 79831.51290684
Deduct 3564 from 4120 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The final outcome is 79831.51290684, with a leftover of 5.56e-07.
