We're dividing 57773297 by 872 
The aim is to understand the frequency of 872 in 57773297.

Going ahead to step 1:
5 divided by 872 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 872

Step 2:
When dividing 57 by 872, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 872

Step 3:
577 divided by 872 is 0 with a remainder of 577.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 577, we get 577.
Fetch the next digit (7) from the dividend, attach it to 577 and continue: 5777 / 872

Moving on to step 4:
The number 872 fits into 5777 6 times, leaving a remainder of 545.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 5232 from 5777 leaves us with 545.
Include the next digit (3) from the dividend after 545, then repeat: 5453 / 872

Step 5:
872 goes into 5453 6 times with a remainder of 221.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 221 after subtracting 5232 from 5453.
Bring next digit (2) of the dividend behind the 221 and repeat the process: 2212 / 872

Let's proceed to step 6:
If we divide 2212 by 872, we get 2 and a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 662.0
Subtract 1744 from 2212 to get 468.
Include the next digit (9) from the dividend after 468, then repeat: 4689 / 872

Moving on to step 7:
4689 divided by 872 is 5 with a remainder of 329.
Use 5 as the next digit of our solution. 
Result so far: 6625.0
If we take 4360 away from 4689, we end up with 329.
Include the next digit (7) from the dividend after 329, then repeat: 3297 / 872

Step 8:
872 goes into 3297 3 times with a remainder of 681.
Put 3 as the next digit of the answer. 
Result so far: 66253.0
Subtracting 2616 from 3297 leaves us with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Advancing to step 9:
The number 872 fits into 6810 7 times, leaving a remainder of 706.
Put 7 as the next digit of the answer. 
Result so far: 66253.7
Deduct 6104 from 6810 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 10:
When dividing 7060 by 872, we get 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 66253.78
If we subtract 6976 from 7060, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
872 goes into 840 0 times with a remainder of 840.
Use 0 as the next digit of our solution. 
Result so far: 66253.78
If we subtract 0 from 840, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 12:
If we divide 8400 by 872, we get 9 and a remainder of 552.
Put 9 as the next digit of the answer. 
Result so far: 66253.7809
Subtract 7848 from 8400 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 13:
When dividing 5520 by 872, we get 6 with a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 66253.78096
Deduct 5232 from 5520 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
872 goes into 2880 3 times with a remainder of 264.
The next digit of our result is 3. 
Result so far: 66253.780963
Subtracting 2616 from 2880 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 15:
872 can be fit into 2640 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 66253.7809633
The remainder is 24 after subtracting 2616 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 66253.7809633, with a leftover of 2.4e-07.
