57977116 ÷ 872 
The aim is to understand the frequency of 872 in 57977116.

Moving on to step 1:
If we divide 5 by 872, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 872

Going ahead to step 2:
57 divided by 872 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 872

Moving on to step 3:
If we divide 579 by 872, we get 0 and a remainder of 579.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 579, we end up with 579.
Bring next digit (7) of the dividend behind the 579 and repeat the process: 5797 / 872

Step 4:
872 goes into 5797 6 times with a remainder of 565.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5232 from 5797, we get 565.
Fetch the next digit (7) from the dividend, attach it to 565 and continue: 5657 / 872

Moving on to step 5:
5657 divided by 872 is 6 with a remainder of 425.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtract 5232 from 5657 to get 425.
Append the next digit (1) from the dividend to 425 and continue with: 4251 / 872

Step 6:
If we divide 4251 by 872, we get 4 and a remainder of 763.
Use 4 as the next digit of our solution. 
Result so far: 664.0
Deduct 3488 from 4251 and we're left with 763.
Bring next digit (1) of the dividend behind the 763 and repeat the process: 7631 / 872

Going ahead to step 7:
When dividing 7631 by 872, we get 8 with a remainder of 655.
Record the quotient 8 as the next digit in the result. 
Result so far: 6648.0
Subtracting 6976 from 7631 leaves us with 655.
Grab the next digit (6) from the dividend, add it to 655, then carry on: 6556 / 872

On to step 8:
872 can be fit into 6556 7 times, resulting in a remainder of 452.
The next digit of our result is 7. 
Result so far: 66487.0
Subtract 6104 from 6556 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 9:
872 goes into 4520 5 times with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 66487.5
Subtracting 4360 from 4520 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
872 goes into 1600 1 times with a remainder of 728.
The next digit of our result is 1. 
Result so far: 66487.51
The remainder is 728 after subtracting 872 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 11:
If we divide 7280 by 872, we get 8 and a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 66487.518
If we take 6976 away from 7280, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 12:
If we divide 3040 by 872, we get 3 and a remainder of 424.
Write down 3 as next digit of the result. 
Result so far: 66487.5183
The remainder is 424 after subtracting 2616 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 13:
The number 872 fits into 4240 4 times, leaving a remainder of 752.
Write down 4 as next digit of the result. 
Result so far: 66487.51834
Subtract 3488 from 4240 to get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 14:
7520 divided by 872 is 8 with a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 66487.518348
If we subtract 6976 from 7520, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 15:
5440 divided by 872 is 6 with a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 66487.5183486
If we take 5232 away from 5440, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
When dividing 2080 by 872, we get 2 with a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 66487.51834862
Deduct 1744 from 2080 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 66487.51834862, with a leftover of 3.36e-07.
