75109172 divided by 53 
We want to divide 75109172 by 53.

Going ahead to step 1:
53 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 53

Moving on to step 2:
The number 53 fits into 75 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 53 from 75 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 53

On to step 3:
53 goes into 221 4 times with a remainder of 9.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 212 from 221 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 53

Advancing to step 4:
The number 53 fits into 90 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Deduct 53 from 90 and we're left with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 53

Step 5:
The number 53 fits into 379 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1417.0
Subtract 371 from 379 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 53

Moving on to step 6:
The number 53 fits into 81 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 14171.0
If we subtract 53 from 81, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 53

On to step 7:
287 divided by 53 is 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 141715.0
Subtracting 265 from 287 leaves us with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 53

Advancing to step 8:
When dividing 222 by 53, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 1417154.0
Deduct 212 from 222 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 53, we get 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1417154.1
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 10:
When dividing 470 by 53, we get 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 1417154.18
Subtracting 424 from 470 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
460 divided by 53 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1417154.188
Subtracting 424 from 460 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 1417154.188 with a remainder of 0.0036.
