74350864 divided by 815 
We want to divide 74350864 by 815.

Advancing to step 1:
The number 815 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 815

Moving on to step 2:
74 divided by 815 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 815

On to step 3:
The number 815 fits into 743 0 times, leaving a remainder of 743.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 743 leaves us with 743.
Include the next digit (5) from the dividend after 743, then repeat: 7435 / 815

Step 4:
The number 815 fits into 7435 9 times, leaving a remainder of 100.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 7335 from 7435 to get 100.
Take the next digit (0) from the dividend and append it to 100, then repeat: 1000 / 815

Step 5:
The number 815 fits into 1000 1 times, leaving a remainder of 185.
The next digit of our result is 1. 
Result so far: 91.0
If we take 815 away from 1000, we end up with 185.
Bring next digit (8) of the dividend behind the 185 and repeat the process: 1858 / 815

Let's proceed to step 6:
1858 divided by 815 is 2 with a remainder of 228.
The next digit of our result is 2. 
Result so far: 912.0
Subtract 1630 from 1858 to get 228.
Fetch the next digit (6) from the dividend, attach it to 228 and continue: 2286 / 815

Step 7:
815 goes into 2286 2 times with a remainder of 656.
Record the quotient 2 as the next digit in the result. 
Result so far: 9122.0
Subtracting 1630 from 2286 leaves us with 656.
Append the next digit (4) from the dividend to 656 and continue with: 6564 / 815

Going ahead to step 8:
6564 divided by 815 is 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 91228.0
Subtracting 6520 from 6564 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
815 goes into 440 0 times with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 91228.0
The remainder is 440 after subtracting 0 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
When dividing 4400 by 815, we get 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 91228.05
The remainder is 325 after subtracting 4075 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 11:
The number 815 fits into 3250 3 times, leaving a remainder of 805.
The next digit of our result is 3. 
Result so far: 91228.053
Deduct 2445 from 3250 and we're left with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Let's proceed to step 12:
8050 divided by 815 is 9 with a remainder of 715.
Put 9 as the next digit of the answer. 
Result so far: 91228.0539
If we subtract 7335 from 8050, we get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 13:
815 goes into 7150 8 times with a remainder of 630.
Use 8 as the next digit of our solution. 
Result so far: 91228.05398
Subtract 6520 from 7150 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 14:
The number 815 fits into 6300 7 times, leaving a remainder of 595.
Write down 7 as next digit of the result. 
Result so far: 91228.053987
If we subtract 5705 from 6300, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 15:
815 goes into 5950 7 times with a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 91228.0539877
The remainder is 245 after subtracting 5705 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final outcome is 91228.0539877, with a leftover of 2.45e-06.
