Let's divide 373413 by 86
The aim is to understand the frequency of 86 in 373413.

Advancing to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 86

Let's proceed to step 2:
If we divide 37 by 86, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 86

Advancing to step 3:
When dividing 373 by 86, we get 4 with a remainder of 29.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 29 after subtracting 344 from 373.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 86

Step 4:
When dividing 294 by 86, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 258 from 294, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 86

Going ahead to step 5:
If we divide 361 by 86, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Subtract 344 from 361 to get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 86

Moving on to step 6:
The number 86 fits into 173 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 4342.0
Subtract 172 from 173 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 86 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4342.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 4342.01
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 4342.011
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 4342.011 and a remainder of 0.0054.
