Let's divide 73136298 by 810
We want to figure out the number of times 73136298 can be divided by 810.

On to step 1:
810 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 810

Moving on to step 2:
810 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 810

On to step 3:
If we divide 731 by 810, we get 0 and a remainder of 731.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 731, we end up with 731.
Include the next digit (3) from the dividend after 731, then repeat: 7313 / 810

On to step 4:
810 goes into 7313 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7290 from 7313 leaves us with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 810

On to step 5:
810 can be fit into 236 0 times, resulting in a remainder of 236.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 236 to get 236.
Fetch the next digit (2) from the dividend, attach it to 236 and continue: 2362 / 810

On to step 6:
2362 divided by 810 is 2 with a remainder of 742.
Write down 2 as next digit of the result. 
Result so far: 902.0
The remainder is 742 after subtracting 1620 from 2362.
Grab the next digit (9) from the dividend, add it to 742, then carry on: 7429 / 810

On to step 7:
The number 810 fits into 7429 9 times, leaving a remainder of 139.
The next digit of our result is 9. 
Result so far: 9029.0
Subtract 7290 from 7429 to get 139.
Take the next digit (8) from the dividend and append it to 139, then repeat: 1398 / 810

Going ahead to step 8:
If we divide 1398 by 810, we get 1 and a remainder of 588.
Use 1 as the next digit of our solution. 
Result so far: 90291.0
The remainder is 588 after subtracting 810 from 1398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 9:
810 goes into 5880 7 times with a remainder of 210.
Record the quotient 7 as the next digit in the result. 
Result so far: 90291.7
Subtracting 5670 from 5880 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
When dividing 2100 by 810, we get 2 with a remainder of 480.
The next digit of our result is 2. 
Result so far: 90291.72
If we take 1620 away from 2100, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
4800 divided by 810 is 5 with a remainder of 750.
The next digit of our result is 5. 
Result so far: 90291.725
The remainder is 750 after subtracting 4050 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 12:
If we divide 7500 by 810, we get 9 and a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 90291.7259
Subtracting 7290 from 7500 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 13:
810 can be fit into 2100 2 times, resulting in a remainder of 480.
Record the quotient 2 as the next digit in the result. 
Result so far: 90291.72592
Subtracting 1620 from 2100 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
810 can be fit into 4800 5 times, resulting in a remainder of 750.
Put 5 as the next digit of the answer. 
Result so far: 90291.725925
Subtract 4050 from 4800 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 15:
810 can be fit into 7500 9 times, resulting in a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 90291.7259259
The remainder is 210 after subtracting 7290 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 16:
If we divide 2100 by 810, we get 2 and a remainder of 480.
Write down 2 as next digit of the result. 
Result so far: 90291.72592592
Subtract 1620 from 2100 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

After the division, we end up with 90291.72592592 and a remainder of 4.8e-07.
