79977474 ÷ 810 
We're looking to find how many times 810 goes into 79977474.

Moving on to step 1:
7 divided by 810 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 810

Advancing to step 2:
The number 810 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 810

On to step 3:
The number 810 fits into 799 0 times, leaving a remainder of 799.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 799 leaves us with 799.
Bring next digit (7) of the dividend behind the 799 and repeat the process: 7997 / 810

Going ahead to step 4:
If we divide 7997 by 810, we get 9 and a remainder of 707.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 7290 from 7997 and we're left with 707.
Grab the next digit (7) from the dividend, add it to 707, then carry on: 7077 / 810

On to step 5:
When dividing 7077 by 810, we get 8 with a remainder of 597.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Deduct 6480 from 7077 and we're left with 597.
Append the next digit (4) from the dividend to 597 and continue with: 5974 / 810

Moving on to step 6:
The number 810 fits into 5974 7 times, leaving a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
Deduct 5670 from 5974 and we're left with 304.
Grab the next digit (7) from the dividend, add it to 304, then carry on: 3047 / 810

On to step 7:
The number 810 fits into 3047 3 times, leaving a remainder of 617.
Put 3 as the next digit of the answer. 
Result so far: 9873.0
Subtracting 2430 from 3047 leaves us with 617.
Grab the next digit (4) from the dividend, add it to 617, then carry on: 6174 / 810

Step 8:
810 goes into 6174 7 times with a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 98737.0
The remainder is 504 after subtracting 5670 from 6174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 9:
If we divide 5040 by 810, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 98737.6
The remainder is 180 after subtracting 4860 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
If we divide 1800 by 810, we get 2 and a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 98737.62
Deduct 1620 from 1800 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
When dividing 1800 by 810, we get 2 with a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 98737.622
If we subtract 1620 from 1800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 98737.622, and the remainder is 0.018.
