We're dividing 43477373 by 125 
The aim is to understand the frequency of 125 in 43477373.

Step 1:
4 divided by 125 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 125

Going ahead to step 2:
43 divided by 125 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 125

On to step 3:
434 divided by 125 is 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 59 after subtracting 375 from 434.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 125

Going ahead to step 4:
597 divided by 125 is 4 with a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 500 from 597 leaves us with 97.
Grab the next digit (7) from the dividend, add it to 97, then carry on: 977 / 125

On to step 5:
977 divided by 125 is 7 with a remainder of 102.
Write down 7 as next digit of the result. 
Result so far: 347.0
Deduct 875 from 977 and we're left with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 125

On to step 6:
When dividing 1023 by 125, we get 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 3478.0
The remainder is 23 after subtracting 1000 from 1023.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 125

On to step 7:
The number 125 fits into 237 1 times, leaving a remainder of 112.
The next digit of our result is 1. 
Result so far: 34781.0
The remainder is 112 after subtracting 125 from 237.
Bring next digit (3) of the dividend behind the 112 and repeat the process: 1123 / 125

On to step 8:
1123 divided by 125 is 8 with a remainder of 123.
Put 8 as the next digit of the answer. 
Result so far: 347818.0
The remainder is 123 after subtracting 1000 from 1123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
The number 125 fits into 1230 9 times, leaving a remainder of 105.
The next digit of our result is 9. 
Result so far: 347818.9
Subtracting 1125 from 1230 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.

On to step 10:
125 can be fit into 1050 8 times, resulting in a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 347818.98
If we subtract 1000 from 1050, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 125, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 347818.984
Subtracting 500 from 500 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
125 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 347818.984
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
The number 125 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 347818.984
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 347818.984 with a remainder of 0.0.
