We divide 609138 by 86
The aim is to understand the frequency of 86 in 609138.

Moving on to step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 86

Going ahead to step 2:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 86

Going ahead to step 3:
The number 86 fits into 609 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 602 from 609 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 86

Step 4:
The number 86 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 86

Step 5:
713 divided by 86 is 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 708.0
If we subtract 688 from 713, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 86

Let's proceed to step 6:
If we divide 258 by 86, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 7083.0
If we take 258 away from 258, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 86 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7083.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
86 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7083.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7083.0, and the remainder is 0.0.
