We look at the division of 2020488 by 879 
The aim is to understand the frequency of 879 in 2020488.

Moving on to step 1:
If we divide 2 by 879, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 879

On to step 2:
20 divided by 879 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 879

Advancing to step 3:
879 goes into 202 0 times with a remainder of 202.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 202 and we're left with 202.
Fetch the next digit (0) from the dividend, attach it to 202 and continue: 2020 / 879

On to step 4:
879 goes into 2020 2 times with a remainder of 262.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1758 from 2020 leaves us with 262.
Take the next digit (4) from the dividend and append it to 262, then repeat: 2624 / 879

Moving on to step 5:
When dividing 2624 by 879, we get 2 with a remainder of 866.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1758 from 2624, we get 866.
Fetch the next digit (8) from the dividend, attach it to 866 and continue: 8668 / 879

Advancing to step 6:
The number 879 fits into 8668 9 times, leaving a remainder of 757.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we subtract 7911 from 8668, we get 757.
Bring next digit (8) of the dividend behind the 757 and repeat the process: 7578 / 879

On to step 7:
879 can be fit into 7578 8 times, resulting in a remainder of 546.
Record the quotient 8 as the next digit in the result. 
Result so far: 2298.0
If we take 7032 away from 7578, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 8:
If we divide 5460 by 879, we get 6 and a remainder of 186.
Write down 6 as next digit of the result. 
Result so far: 2298.6
Subtracting 5274 from 5460 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 9:
1860 divided by 879 is 2 with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 2298.62
Subtract 1758 from 1860 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
If we divide 1020 by 879, we get 1 and a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 2298.621
The remainder is 141 after subtracting 879 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 11:
If we divide 1410 by 879, we get 1 and a remainder of 531.
Write down 1 as next digit of the result. 
Result so far: 2298.6211
Subtracting 879 from 1410 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

The final outcome is 2298.6211, with a leftover of 0.00531.
