Let's divide 77535641 by 875
The aim is to understand the frequency of 875 in 77535641.

On to step 1:
875 can be fit into 7 0 times, resulting in 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.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 875

Going ahead to step 2:
875 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 875

Advancing to step 3:
775 divided by 875 is 0 with a remainder of 775.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 775 to get 775.
Append the next digit (3) from the dividend to 775 and continue with: 7753 / 875

On to step 4:
If we divide 7753 by 875, we get 8 and a remainder of 753.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7000 from 7753, we get 753.
Bring next digit (5) of the dividend behind the 753 and repeat the process: 7535 / 875

Moving on to step 5:
7535 divided by 875 is 8 with a remainder of 535.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 535 after subtracting 7000 from 7535.
Append the next digit (6) from the dividend to 535 and continue with: 5356 / 875

Advancing to step 6:
5356 divided by 875 is 6 with a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 886.0
The remainder is 106 after subtracting 5250 from 5356.
Include the next digit (4) from the dividend after 106, then repeat: 1064 / 875

Let's proceed to step 7:
875 goes into 1064 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 8861.0
If we take 875 away from 1064, we end up with 189.
Include the next digit (1) from the dividend after 189, then repeat: 1891 / 875

Step 8:
When dividing 1891 by 875, we get 2 with a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 88612.0
Subtracting 1750 from 1891 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
1410 divided by 875 is 1 with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 88612.1
If we subtract 875 from 1410, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
If we divide 5350 by 875, we get 6 and a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 88612.16
If we take 5250 away from 5350, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
875 goes into 1000 1 times with a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 88612.161
Subtract 875 from 1000 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
875 can be fit into 1250 1 times, resulting in a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 88612.1611
Subtracting 875 from 1250 leaves us 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.

The quotient of the division is 88612.1611, and the remainder is 0.00375.
