274605 divided by 86 
The aim is to understand the frequency of 86 in 274605.

Moving on to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 86

Going ahead to step 2:
86 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 86

Moving on to step 3:
86 can be fit into 274 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 258 from 274 to get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 86

Step 4:
The number 86 fits into 166 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 86 from 166 and we're left with 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 86

On to step 5:
86 can be fit into 800 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 319.0
Subtracting 774 from 800 leaves us with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 86

Moving on to step 6:
265 divided by 86 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3193.0
Subtract 258 from 265 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 86, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3193.0
If we take 0 away from 70, 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.

Going ahead to step 8:
When dividing 700 by 86, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3193.08
If we take 688 away from 700, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 86, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 3193.081
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
86 goes into 340 3 times with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 3193.0813
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
When dividing 820 by 86, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3193.08139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3193.081395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 86 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3193.0813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
When dividing 420 by 86, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 3193.08139534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 3193.08139534 with a remainder of 7.6e-08.
