We're dividing 85866283 by 279 
The aim is to understand the frequency of 279 in 85866283.

On to step 1:
8 divided by 279 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 279

Going ahead to step 2:
The number 279 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 279

Moving on to step 3:
The number 279 fits into 858 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 21 after subtracting 837 from 858.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 279

Step 4:
216 divided by 279 is 0 with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 216 to get 216.
Append the next digit (6) from the dividend to 216 and continue with: 2166 / 279

Moving on to step 5:
279 goes into 2166 7 times with a remainder of 213.
Write down 7 as next digit of the result. 
Result so far: 307.0
The remainder is 213 after subtracting 1953 from 2166.
Include the next digit (2) from the dividend after 213, then repeat: 2132 / 279

On to step 6:
The number 279 fits into 2132 7 times, leaving a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 3077.0
If we take 1953 away from 2132, we end up with 179.
Take the next digit (8) from the dividend and append it to 179, then repeat: 1798 / 279

Step 7:
When dividing 1798 by 279, we get 6 with a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 30776.0
Deduct 1674 from 1798 and we're left with 124.
Take the next digit (3) from the dividend and append it to 124, then repeat: 1243 / 279

Step 8:
When dividing 1243 by 279, we get 4 with a remainder of 127.
Write down 4 as next digit of the result. 
Result so far: 307764.0
If we take 1116 away from 1243, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
279 goes into 1270 4 times with a remainder of 154.
The number 4 becomes the next digit in our result. 
Result so far: 307764.4
If we take 1116 away from 1270, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 10:
279 goes into 1540 5 times with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 307764.45
If we subtract 1395 from 1540, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 11:
279 goes into 1450 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 307764.455
The remainder is 55 after subtracting 1395 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 307764.455, and the remainder is 0.0055.
