Let's divide 725370 by 86
The aim is to understand the frequency of 86 in 725370.

On to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 86

Advancing to step 2:
When dividing 72 by 86, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 86

Let's proceed to step 3:
The number 86 fits into 725 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 688 from 725 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 86

Step 4:
86 goes into 373 4 times with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtract 344 from 373 to get 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 86

Step 5:
The number 86 fits into 297 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 843.0
Subtract 258 from 297 to get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 86

Step 6:
When dividing 390 by 86, we get 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 8434.0
Subtract 344 from 390 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
If we divide 460 by 86, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8434.5
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 86, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 8434.53
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 86, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 8434.534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
When dividing 760 by 86, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 8434.5348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
When dividing 720 by 86, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8434.53488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 8434.53488 with a remainder of 3.2e-05.
