78922029 ÷ 81 
We're looking to find how many times 81 goes into 78922029.

Going ahead to step 1:
81 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 81

On to step 2:
If we divide 78 by 81, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 81

Step 3:
789 divided by 81 is 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 729 from 789, we get 60.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 81

On to step 4:
The number 81 fits into 602 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 567 from 602 to get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 81

Advancing to step 5:
If we divide 352 by 81, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
Subtracting 324 from 352 leaves us with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 81

Going ahead to step 6:
280 divided by 81 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 9743.0
The remainder is 37 after subtracting 243 from 280.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 81

On to step 7:
372 divided by 81 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 97434.0
If we subtract 324 from 372, we get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 81

Moving on to step 8:
81 can be fit into 489 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 974346.0
Subtracting 486 from 489 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 974346.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
If we divide 300 by 81, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 974346.03
If we subtract 243 from 300, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
81 can be fit into 570 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 974346.037
Subtracting 567 from 570 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
81 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 974346.037
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 81 fits into 300 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 974346.03703
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 14:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 974346.037037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 15:
81 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 974346.037037
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
81 goes into 300 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 974346.03703703
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 974346.03703703 and a remainder of 5.7e-08.
