We look at the division of 629460 by 86 
The aim is to understand the frequency of 86 in 629460.

Let's proceed to step 1:
6 divided by 86 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 86

Moving on to step 2:
86 goes into 62 0 times with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 86

Going ahead to step 3:
629 divided by 86 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 602 from 629, we get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 86

Going ahead to step 4:
If we divide 274 by 86, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 16 after subtracting 258 from 274.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 86

Advancing to step 5:
166 divided by 86 is 1 with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 731.0
If we take 86 away from 166, we end up with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 86

Advancing to step 6:
If we divide 800 by 86, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 7319.0
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
86 goes into 260 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 7319.3
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
86 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7319.3
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 7319.302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
280 divided by 86 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 7319.3023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 86, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 7319.30232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7319.302325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
The number 86 fits into 500 5 times, leaving a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7319.3023255
Subtracting 430 from 500 leaves us 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.

Our division results in 7319.3023255 with a remaining 7e-07.
