988343 divided by 86 
The aim is to understand the frequency of 86 in 988343.

Moving on to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 86

Let's proceed to step 2:
98 divided by 86 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 86 from 98.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 86

Advancing to step 3:
If we divide 128 by 86, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 86 from 128, we get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 86

Step 4:
When dividing 423 by 86, we get 4 with a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 344 away from 423, we end up with 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 86

On to step 5:
When dividing 794 by 86, we get 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 1149.0
Subtract 774 from 794 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 86

Step 6:
203 divided by 86 is 2 with a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 11492.0
The remainder is 31 after subtracting 172 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
86 goes into 310 3 times with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 11492.3
If we subtract 258 from 310, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
86 goes into 520 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11492.36
Subtracting 516 from 520 leaves us 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.

Advancing to step 9:
When dividing 40 by 86, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11492.36
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 10:
When dividing 400 by 86, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 11492.3604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 11492.36046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
If we divide 440 by 86, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11492.360465
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.

Moving on to step 13:
If we divide 100 by 86, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 11492.3604651
Deduct 86 from 100 and we're left 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.

Let's proceed to step 14:
140 divided by 86 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 11492.36046511
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.

The quotient of the division is 11492.36046511, and the remainder is 5.4e-08.
