27871641 ÷ 579 
The aim is to understand the frequency of 579 in 27871641.

Advancing to step 1:
If we divide 2 by 579, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 579

Going ahead to step 2:
If we divide 27 by 579, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 579

On to step 3:
If we divide 278 by 579, we get 0 and a remainder of 278.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 278, we end up with 278.
Append the next digit (7) from the dividend to 278 and continue with: 2787 / 579

Going ahead to step 4:
When dividing 2787 by 579, we get 4 with a remainder of 471.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 471 after subtracting 2316 from 2787.
Grab the next digit (1) from the dividend, add it to 471, then carry on: 4711 / 579

On to step 5:
When dividing 4711 by 579, we get 8 with a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 4632 from 4711, we get 79.
Include the next digit (6) from the dividend after 79, then repeat: 796 / 579

On to step 6:
When dividing 796 by 579, we get 1 with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 481.0
Deduct 579 from 796 and we're left with 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 579

On to step 7:
The number 579 fits into 2174 3 times, leaving a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 4813.0
If we take 1737 away from 2174, we end up with 437.
Fetch the next digit (1) from the dividend, attach it to 437 and continue: 4371 / 579

On to step 8:
579 can be fit into 4371 7 times, resulting in a remainder of 318.
Put 7 as the next digit of the answer. 
Result so far: 48137.0
If we take 4053 away from 4371, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
579 goes into 3180 5 times with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 48137.5
Subtract 2895 from 3180 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 10:
If we divide 2850 by 579, we get 4 and a remainder of 534.
The number 4 becomes the next digit in our result. 
Result so far: 48137.54
Deduct 2316 from 2850 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 11:
5340 divided by 579 is 9 with a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 48137.549
Subtract 5211 from 5340 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 12:
1290 divided by 579 is 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 48137.5492
If we take 1158 away from 1290, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 13:
The number 579 fits into 1320 2 times, leaving a remainder of 162.
Record the quotient 2 as the next digit in the result. 
Result so far: 48137.54922
Subtract 1158 from 1320 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 48137.54922, with a leftover of 0.000162.
