We look at the division of 87460722 by 125 
The aim is to understand the frequency of 125 in 87460722.

Step 1:
125 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 125

On to step 2:
125 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (4) from the dividend, attach it to 87 and continue: 874 / 125

Advancing to step 3:
When dividing 874 by 125, we get 6 with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 124 after subtracting 750 from 874.
Include the next digit (6) from the dividend after 124, then repeat: 1246 / 125

On to step 4:
125 can be fit into 1246 9 times, resulting in a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Deduct 1125 from 1246 and we're left with 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 125

On to step 5:
When dividing 1210 by 125, we get 9 with a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 699.0
Subtracting 1125 from 1210 leaves us with 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 125

Moving on to step 6:
If we divide 857 by 125, we get 6 and a remainder of 107.
Use 6 as the next digit of our solution. 
Result so far: 6996.0
Deduct 750 from 857 and we're left with 107.
Include the next digit (2) from the dividend after 107, then repeat: 1072 / 125

Let's proceed to step 7:
125 can be fit into 1072 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 69968.0
Deduct 1000 from 1072 and we're left with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 125

Moving on to step 8:
125 can be fit into 722 5 times, resulting in a remainder of 97.
The number 5 becomes the next digit in our result. 
Result so far: 699685.0
If we subtract 625 from 722, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 125 is 7 with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 699685.7
Subtract 875 from 970 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 10:
125 goes into 950 7 times with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 699685.77
If we subtract 875 from 950, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 699685.77, and the remainder is 0.075.
