We're dividing 75099 by 61 
We want to figure out the number of times 75099 can be divided by 61.

Let's proceed to step 1:
7 divided by 61 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 61

On to step 2:
If we divide 75 by 61, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 61 from 75 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 61

Advancing to step 3:
140 divided by 61 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 122 away from 140, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 61

On to step 4:
If we divide 189 by 61, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 123.0
The remainder is 6 after subtracting 183 from 189.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 61

Going ahead to step 5:
61 can be fit into 69 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1231.0
Subtracting 61 from 69 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
61 can be fit into 80 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1231.1
If we take 61 away from 80, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
61 goes into 190 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1231.13
Subtract 183 from 190 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 61, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1231.131
If we subtract 61 from 70, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
61 can be fit into 90 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1231.1311
If we take 61 away from 90, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 1231.1311, and the remainder is 0.00029.
