We're dividing 79125009 by 337 
The aim is to understand the frequency of 337 in 79125009.

Going ahead to step 1:
If we divide 7 by 337, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 337

On to step 2:
If we divide 79 by 337, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 337

Advancing to step 3:
337 can be fit into 791 2 times, resulting in a remainder of 117.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 674 from 791, we get 117.
Include the next digit (2) from the dividend after 117, then repeat: 1172 / 337

Moving on to step 4:
337 goes into 1172 3 times with a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 161 after subtracting 1011 from 1172.
Append the next digit (5) from the dividend to 161 and continue with: 1615 / 337

Going ahead to step 5:
337 can be fit into 1615 4 times, resulting in a remainder of 267.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 1348 from 1615 leaves us with 267.
Grab the next digit (0) from the dividend, add it to 267, then carry on: 2670 / 337

Advancing to step 6:
When dividing 2670 by 337, we get 7 with a remainder of 311.
Record the quotient 7 as the next digit in the result. 
Result so far: 2347.0
If we subtract 2359 from 2670, we get 311.
Include the next digit (0) from the dividend after 311, then repeat: 3110 / 337

Going ahead to step 7:
3110 divided by 337 is 9 with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 23479.0
If we subtract 3033 from 3110, we get 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 337

Advancing to step 8:
337 goes into 779 2 times with a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 234792.0
Subtracting 674 from 779 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
When dividing 1050 by 337, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 234792.3
Subtract 1011 from 1050 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
390 divided by 337 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 234792.31
The remainder is 53 after subtracting 337 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
530 divided by 337 is 1 with a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 234792.311
If we take 337 away from 530, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

The final outcome is 234792.311, with a leftover of 0.0193.
