900263 divided by 86 
The aim is to understand the frequency of 86 in 900263.

Let's proceed 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
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 86

Advancing to step 2:
When dividing 90 by 86, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 86 from 90 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 86

On to step 3:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 86

Moving on to step 4:
86 goes into 402 4 times with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 104.0
Subtract 344 from 402 to get 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 86

On to step 5:
86 can be fit into 586 6 times, resulting in a remainder of 70.
The next digit of our result is 6. 
Result so far: 1046.0
Deduct 516 from 586 and we're left with 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 86

On to step 6:
703 divided by 86 is 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 10468.0
If we subtract 688 from 703, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
86 goes into 150 1 times with a remainder of 64.
The next digit of our result is 1. 
Result so far: 10468.1
The remainder is 64 after subtracting 86 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 10468.17
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
380 divided by 86 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 10468.174
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 10468.1744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10468.1744 and a remainder of 0.00016.
