Let's divide 874789 by 81
We want to figure out the number of times 874789 can be divided by 81.

Let's proceed to step 1:
8 divided by 81 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 81

On to step 2:
The number 81 fits into 87 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 87, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 81

Going ahead to step 3:
When dividing 64 by 81, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 81

Going ahead to step 4:
If we divide 647 by 81, we get 7 and a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 567 from 647 leaves us with 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 81

Moving on to step 5:
If we divide 808 by 81, we get 9 and a remainder of 79.
The next digit of our result is 9. 
Result so far: 1079.0
If we take 729 away from 808, we end up with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 81

Let's proceed to step 6:
81 goes into 799 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 10799.0
Deduct 729 from 799 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
700 divided by 81 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 10799.8
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
81 goes into 520 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 10799.86
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
81 goes into 340 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 10799.864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 10799.8641
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 11:
If we divide 790 by 81, we get 9 and a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 10799.86419
Subtract 729 from 790 to get 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 12:
81 goes into 610 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 10799.864197
Subtract 567 from 610 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
When dividing 430 by 81, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10799.8641975
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
81 goes into 250 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 10799.86419753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 10799.86419753 with a remaining 7e-09.
