3758656 divided by 875 
The aim is to understand the frequency of 875 in 3758656.

On to step 1:
875 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 875

Going ahead to step 2:
875 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 875

Step 3:
When dividing 375 by 875, we get 0 with a remainder of 375.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 375 to get 375.
Fetch the next digit (8) from the dividend, attach it to 375 and continue: 3758 / 875

Let's proceed to step 4:
875 can be fit into 3758 4 times, resulting in a remainder of 258.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 258 after subtracting 3500 from 3758.
Grab the next digit (6) from the dividend, add it to 258, then carry on: 2586 / 875

Step 5:
2586 divided by 875 is 2 with a remainder of 836.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 1750 from 2586 leaves us with 836.
Append the next digit (5) from the dividend to 836 and continue with: 8365 / 875

Going ahead to step 6:
875 can be fit into 8365 9 times, resulting in a remainder of 490.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
Deduct 7875 from 8365 and we're left with 490.
Append the next digit (6) from the dividend to 490 and continue with: 4906 / 875

Moving on to step 7:
If we divide 4906 by 875, we get 5 and a remainder of 531.
Use 5 as the next digit of our solution. 
Result so far: 4295.0
The remainder is 531 after subtracting 4375 from 4906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 8:
When dividing 5310 by 875, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4295.6
The remainder is 60 after subtracting 5250 from 5310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
When dividing 600 by 875, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 4295.6
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 10:
If we divide 6000 by 875, we get 6 and a remainder of 750.
Record the quotient 6 as the next digit in the result. 
Result so far: 4295.606
Subtracting 5250 from 6000 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
875 can be fit into 7500 8 times, resulting in a remainder of 500.
The number 8 becomes the next digit in our result. 
Result so far: 4295.6068
Subtracting 7000 from 7500 leaves us 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.

Let's proceed to step 12:
The number 875 fits into 5000 5 times, leaving a remainder of 625.
The number 5 becomes the next digit in our result. 
Result so far: 4295.60685
Subtract 4375 from 5000 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 13:
875 can be fit into 6250 7 times, resulting in a remainder of 125.
The number 7 becomes the next digit in our result. 
Result so far: 4295.606857
The remainder is 125 after subtracting 6125 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 14:
875 goes into 1250 1 times with a remainder of 375.
The next digit of our result is 1. 
Result so far: 4295.6068571
Deduct 875 from 1250 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 15:
3750 divided by 875 is 4 with a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 4295.60685714
Subtract 3500 from 3750 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 4295.60685714, with a leftover of 2.5e-07.
