We look at the division of 55271903 by 879 
The aim is to understand the frequency of 879 in 55271903.

Let's proceed to step 1:
When dividing 5 by 879, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 879

Advancing to step 2:
If we divide 55 by 879, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 879

Going ahead to step 3:
879 goes into 552 0 times with a remainder of 552.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 552 to get 552.
Grab the next digit (7) from the dividend, add it to 552, then carry on: 5527 / 879

On to step 4:
If we divide 5527 by 879, we get 6 and a remainder of 253.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 253 after subtracting 5274 from 5527.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 879

Moving on to step 5:
879 goes into 2531 2 times with a remainder of 773.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Deduct 1758 from 2531 and we're left with 773.
Bring next digit (9) of the dividend behind the 773 and repeat the process: 7739 / 879

Step 6:
The number 879 fits into 7739 8 times, leaving a remainder of 707.
The next digit of our result is 8. 
Result so far: 628.0
If we subtract 7032 from 7739, we get 707.
Take the next digit (0) from the dividend and append it to 707, then repeat: 7070 / 879

Step 7:
879 can be fit into 7070 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 6288.0
The remainder is 38 after subtracting 7032 from 7070.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 879

Advancing to step 8:
879 goes into 383 0 times with a remainder of 383.
The next digit of our result is 0. 
Result so far: 62880.0
If we take 0 away from 383, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 9:
879 can be fit into 3830 4 times, resulting in a remainder of 314.
The number 4 becomes the next digit in our result. 
Result so far: 62880.4
Subtracting 3516 from 3830 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
The number 879 fits into 3140 3 times, leaving a remainder of 503.
The number 3 becomes the next digit in our result. 
Result so far: 62880.43
If we subtract 2637 from 3140, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 11:
879 can be fit into 5030 5 times, resulting in a remainder of 635.
Use 5 as the next digit of our solution. 
Result so far: 62880.435
Subtract 4395 from 5030 to get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 12:
6350 divided by 879 is 7 with a remainder of 197.
The next digit of our result is 7. 
Result so far: 62880.4357
The remainder is 197 after subtracting 6153 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 13:
If we divide 1970 by 879, we get 2 and a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 62880.43572
If we take 1758 away from 1970, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 14:
2120 divided by 879 is 2 with a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 62880.435722
Subtracting 1758 from 2120 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The quotient of the division is 62880.435722, and the remainder is 3.62e-05.
