904613 divided by 86 
The aim is to understand the frequency of 86 in 904613.

Going ahead to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 86

Let's proceed to step 2:
86 can be fit into 90 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 86 from 90 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 86

Advancing to step 3:
The number 86 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 44, we get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 86

Step 4:
86 goes into 446 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 105.0
If we take 430 away from 446, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 86

On to step 5:
When dividing 161 by 86, we get 1 with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 1051.0
The remainder is 75 after subtracting 86 from 161.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 86

Step 6:
If we divide 753 by 86, we get 8 and a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 10518.0
If we take 688 away from 753, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
86 can be fit into 650 7 times, resulting in a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 10518.7
If we take 602 away from 650, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10518.75
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 10518.755
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 10518.755, and the remainder is 0.007.
