We look at the division of 75499691 by 623 
We want to divide 75499691 by 623.

On to step 1:
When dividing 7 by 623, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 623

Moving on to step 2:
When dividing 75 by 623, we get 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 623

Going ahead to step 3:
When dividing 754 by 623, we get 1 with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 623 from 754 leaves us with 131.
Append the next digit (9) from the dividend to 131 and continue with: 1319 / 623

Moving on to step 4:
623 goes into 1319 2 times with a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1246 from 1319, we get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 623

Step 5:
When dividing 739 by 623, we get 1 with a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 121.0
The remainder is 116 after subtracting 623 from 739.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 623

On to step 6:
623 can be fit into 1166 1 times, resulting in a remainder of 543.
Write down 1 as next digit of the result. 
Result so far: 1211.0
Subtracting 623 from 1166 leaves us with 543.
Take the next digit (9) from the dividend and append it to 543, then repeat: 5439 / 623

Let's proceed to step 7:
When dividing 5439 by 623, we get 8 with a remainder of 455.
Record the quotient 8 as the next digit in the result. 
Result so far: 12118.0
If we take 4984 away from 5439, we end up with 455.
Take the next digit (1) from the dividend and append it to 455, then repeat: 4551 / 623

Let's proceed to step 8:
4551 divided by 623 is 7 with a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 121187.0
Deduct 4361 from 4551 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
623 can be fit into 1900 3 times, resulting in a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 121187.3
Subtracting 1869 from 1900 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 623 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 121187.3
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 11:
623 can be fit into 3100 4 times, resulting in a remainder of 608.
Record the quotient 4 as the next digit in the result. 
Result so far: 121187.304
If we take 2492 away from 3100, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 12:
623 goes into 6080 9 times with a remainder of 473.
The next digit of our result is 9. 
Result so far: 121187.3049
If we subtract 5607 from 6080, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Step 13:
4730 divided by 623 is 7 with a remainder of 369.
Record the quotient 7 as the next digit in the result. 
Result so far: 121187.30497
If we take 4361 away from 4730, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 14:
The number 623 fits into 3690 5 times, leaving a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 121187.304975
If we subtract 3115 from 3690, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 15:
5750 divided by 623 is 9 with a remainder of 143.
Record the quotient 9 as the next digit in the result. 
Result so far: 121187.3049759
If we take 5607 away from 5750, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 16:
The number 623 fits into 1430 2 times, leaving a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 121187.30497592
Deduct 1246 from 1430 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

After the division, we end up with 121187.30497592 and a remainder of 1.84e-07.
