We're dividing 81310842 by 89 
We want to figure out the number of times 81310842 can be divided by 89.

Moving on to step 1:
When dividing 8 by 89, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 89

Advancing to step 2:
If we divide 81 by 89, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 89

Going ahead to step 3:
89 goes into 813 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 801 away from 813, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 89

Step 4:
89 goes into 121 1 times with a remainder of 32.
The next digit of our result is 1. 
Result so far: 91.0
If we take 89 away from 121, we end up with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 89

Advancing to step 5:
If we divide 320 by 89, we get 3 and a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 913.0
If we take 267 away from 320, we end up with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 89

Going ahead to step 6:
If we divide 538 by 89, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9136.0
Subtracting 534 from 538 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 89

Going ahead to step 7:
The number 89 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 91360.0
If we subtract 0 from 44, we get 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 89

Going ahead to step 8:
89 can be fit into 442 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 913604.0
Subtracting 356 from 442 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
89 goes into 860 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 913604.9
Subtract 801 from 860 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.

Step 10:
89 goes into 590 6 times with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 913604.96
Subtracting 534 from 590 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
When dividing 560 by 89, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 913604.966
Subtract 534 from 560 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 913604.966, and the remainder is 0.0026.
