75510834 divided by 20 
We want to figure out the number of times 75510834 can be divided by 20.

On to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 20

On to step 2:
If we divide 75 by 20, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 15 after subtracting 60 from 75.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

On to step 3:
155 divided by 20 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 140 from 155 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 20

Advancing to step 4:
If we divide 151 by 20, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we subtract 140 from 151, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 20

Step 5:
20 goes into 110 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3775.0
The remainder is 10 after subtracting 100 from 110.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 20

On to step 6:
The number 20 fits into 108 5 times, leaving a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 37755.0
Subtracting 100 from 108 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Moving on to step 7:
The number 20 fits into 83 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 377554.0
Subtract 80 from 83 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Going ahead to step 8:
20 goes into 34 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 3775541.0
The remainder is 14 after subtracting 20 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
20 can be fit into 140 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 3775541.7
The remainder is 0 after subtracting 140 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3775541.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3775541.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 3775541.7 with a balance of 0.0.
