We're dividing 10157037 by 124 
The aim is to understand the frequency of 124 in 10157037.

Advancing to step 1:
When dividing 1 by 124, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 124

Going ahead to step 2:
124 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 124

Moving on to step 3:
The number 124 fits into 101 0 times, leaving a remainder of 101.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Include the next digit (5) from the dividend after 101, then repeat: 1015 / 124

Advancing to step 4:
1015 divided by 124 is 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 992 away from 1015, we end up with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 124

Let's proceed to step 5:
If we divide 237 by 124, we get 1 and a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 124 away from 237, we end up with 113.
Bring next digit (0) of the dividend behind the 113 and repeat the process: 1130 / 124

Advancing to step 6:
If we divide 1130 by 124, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 819.0
Subtract 1116 from 1130 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 124

Going ahead to step 7:
If we divide 143 by 124, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 8191.0
If we subtract 124 from 143, we get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 124

Step 8:
124 goes into 197 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 81911.0
Subtracting 124 from 197 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
730 divided by 124 is 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 81911.5
The remainder is 110 after subtracting 620 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
124 goes into 1100 8 times with a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 81911.58
Subtracting 992 from 1100 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
1080 divided by 124 is 8 with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 81911.588
Subtracting 992 from 1080 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 81911.588 with a remainder of 0.0088.
