81505112 ÷ 753 
We want to figure out the number of times 81505112 can be divided by 753.

Let's proceed to step 1:
753 can be fit into 8 0 times, resulting in 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 753

Moving on to step 2:
753 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 753

Going ahead to step 3:
753 can be fit into 815 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 753 from 815 to get 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 753

Advancing to step 4:
The number 753 fits into 620 0 times, leaving a remainder of 620.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 620, we end up with 620.
Append the next digit (5) from the dividend to 620 and continue with: 6205 / 753

Step 5:
753 can be fit into 6205 8 times, resulting in a remainder of 181.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 181 after subtracting 6024 from 6205.
Grab the next digit (1) from the dividend, add it to 181, then carry on: 1811 / 753

Let's proceed to step 6:
The number 753 fits into 1811 2 times, leaving a remainder of 305.
Put 2 as the next digit of the answer. 
Result so far: 1082.0
Deduct 1506 from 1811 and we're left with 305.
Append the next digit (1) from the dividend to 305 and continue with: 3051 / 753

Moving on to step 7:
If we divide 3051 by 753, we get 4 and a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 10824.0
If we take 3012 away from 3051, we end up with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 753

Advancing to step 8:
753 can be fit into 392 0 times, resulting in a remainder of 392.
Write down 0 as next digit of the result. 
Result so far: 108240.0
Deduct 0 from 392 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 9:
753 goes into 3920 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 108240.5
Subtract 3765 from 3920 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 10:
If we divide 1550 by 753, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 108240.52
Deduct 1506 from 1550 and we're left 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.

Step 11:
440 divided by 753 is 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 108240.52
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
753 can be fit into 4400 5 times, resulting in a remainder of 635.
Record the quotient 5 as the next digit in the result. 
Result so far: 108240.5205
The remainder is 635 after subtracting 3765 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 13:
The number 753 fits into 6350 8 times, leaving a remainder of 326.
Record the quotient 8 as the next digit in the result. 
Result so far: 108240.52058
If we take 6024 away from 6350, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 14:
3260 divided by 753 is 4 with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 108240.520584
Subtracting 3012 from 3260 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 15:
753 can be fit into 2480 3 times, resulting in a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 108240.5205843
If we subtract 2259 from 2480, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 16:
If we divide 2210 by 753, we get 2 and a remainder of 704.
Record the quotient 2 as the next digit in the result. 
Result so far: 108240.52058432
Deduct 1506 from 2210 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

The final result is 108240.52058432 with a remainder of 7.04e-07.
