Let's divide 980631 by 86
The aim is to understand the frequency of 86 in 980631.

Moving on to step 1:
9 divided by 86 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 86

Moving on to step 2:
86 can be fit into 98 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 98 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 86

Advancing to step 3:
86 goes into 120 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 86 away from 120, we end up with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 86

Moving on to step 4:
86 can be fit into 346 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 344 away from 346, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 86

Step 5:
86 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 1140.0
Subtract 0 from 23 to get 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 86

Step 6:
86 can be fit into 231 2 times, resulting in a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 11402.0
If we subtract 172 from 231, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
When dividing 590 by 86, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 11402.6
The remainder is 74 after subtracting 516 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
When dividing 740 by 86, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 11402.68
The remainder is 52 after subtracting 688 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
86 can be fit into 520 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 11402.686
If we take 516 away from 520, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 86, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11402.686
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 86, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 11402.68604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
560 divided by 86 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 11402.686046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
440 divided by 86 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11402.6860465
Deduct 430 from 440 and we're left with 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 14:
86 goes into 100 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 11402.68604651
If we take 86 away from 100, we end up 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.

The final result is 11402.68604651 with a remainder of 1.4e-08.
