We're dividing 75451751 by 131 
We want to figure out the number of times 75451751 can be divided by 131.

On to step 1:
131 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 131

Moving on to step 2:
75 divided by 131 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 131

Step 3:
The number 131 fits into 754 5 times, leaving a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 655 away from 754, we end up with 99.
Bring next digit (5) of the dividend behind the 99 and repeat the process: 995 / 131

Going ahead to step 4:
If we divide 995 by 131, we get 7 and a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 917 from 995 and we're left with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 131

On to step 5:
When dividing 781 by 131, we get 5 with a remainder of 126.
Write down 5 as next digit of the result. 
Result so far: 575.0
Subtracting 655 from 781 leaves us with 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 131

Moving on to step 6:
1267 divided by 131 is 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 5759.0
If we take 1179 away from 1267, we end up with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 131

Advancing to step 7:
885 divided by 131 is 6 with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 57596.0
Deduct 786 from 885 and we're left with 99.
Bring next digit (1) of the dividend behind the 99 and repeat the process: 991 / 131

Let's proceed to step 8:
131 can be fit into 991 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 575967.0
If we take 917 away from 991, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
The number 131 fits into 740 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 575967.5
If we take 655 away from 740, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
131 goes into 850 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 575967.56
Deduct 786 from 850 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
131 goes into 640 4 times with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 575967.564
Deduct 524 from 640 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 12:
131 can be fit into 1160 8 times, resulting in a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 575967.5648
If we subtract 1048 from 1160, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
1120 divided by 131 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 575967.56488
If we subtract 1048 from 1120, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 575967.56488 with a remainder of 7.2e-05.
