83718122 divided by 750 
The aim is to understand the frequency of 750 in 83718122.

On to step 1:
The number 750 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 750

Going ahead to step 2:
83 divided by 750 is 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 750

Step 3:
The number 750 fits into 837 1 times, leaving a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 750 away from 837, we end up with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 750

On to step 4:
If we divide 871 by 750, we get 1 and a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 750 from 871 leaves us with 121.
Grab the next digit (8) from the dividend, add it to 121, then carry on: 1218 / 750

On to step 5:
1218 divided by 750 is 1 with a remainder of 468.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 750 away from 1218, we end up with 468.
Fetch the next digit (1) from the dividend, attach it to 468 and continue: 4681 / 750

Let's proceed to step 6:
750 can be fit into 4681 6 times, resulting in a remainder of 181.
Record the quotient 6 as the next digit in the result. 
Result so far: 1116.0
If we subtract 4500 from 4681, we get 181.
Include the next digit (2) from the dividend after 181, then repeat: 1812 / 750

Step 7:
If we divide 1812 by 750, we get 2 and a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 11162.0
Deduct 1500 from 1812 and we're left with 312.
Include the next digit (2) from the dividend after 312, then repeat: 3122 / 750

Going ahead to step 8:
The number 750 fits into 3122 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 111624.0
If we take 3000 away from 3122, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 9:
1220 divided by 750 is 1 with a remainder of 470.
Put 1 as the next digit of the answer. 
Result so far: 111624.1
Subtracting 750 from 1220 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 10:
If we divide 4700 by 750, we get 6 and a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 111624.16
Subtract 4500 from 4700 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
750 can be fit into 2000 2 times, resulting in a remainder of 500.
Use 2 as the next digit of our solution. 
Result so far: 111624.162
Subtract 1500 from 2000 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
750 can be fit into 5000 6 times, resulting in a remainder of 500.
The next digit of our result is 6. 
Result so far: 111624.1626
Deduct 4500 from 5000 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 13:
5000 divided by 750 is 6 with a remainder of 500.
Put 6 as the next digit of the answer. 
Result so far: 111624.16266
Deduct 4500 from 5000 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 111624.16266, and the remainder is 0.0005.
