Let's divide 57872071 by 126
The aim is to understand the frequency of 126 in 57872071.

On to step 1:
If we divide 5 by 126, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 126

Moving on to step 2:
If we divide 57 by 126, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 126

On to step 3:
If we divide 578 by 126, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 504 from 578, we get 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 126

On to step 4:
126 goes into 747 5 times with a remainder of 117.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 630 away from 747, we end up with 117.
Take the next digit (2) from the dividend and append it to 117, then repeat: 1172 / 126

On to step 5:
126 can be fit into 1172 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 459.0
If we take 1134 away from 1172, we end up with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 126

Step 6:
If we divide 380 by 126, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4593.0
If we subtract 378 from 380, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 126

Moving on to step 7:
126 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 45930.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 126

Moving on to step 8:
126 goes into 271 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 459302.0
Subtract 252 from 271 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
126 goes into 190 1 times with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 459302.1
If we subtract 126 from 190, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
126 can be fit into 640 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 459302.15
Subtract 630 from 640 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
126 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 459302.15
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
126 goes into 1000 7 times with a remainder of 118.
The number 7 becomes the next digit in our result. 
Result so far: 459302.1507
If we take 882 away from 1000, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 13:
If we divide 1180 by 126, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 459302.15079
Subtracting 1134 from 1180 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
460 divided by 126 is 3 with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 459302.150793
If we take 378 away from 460, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 15:
126 can be fit into 820 6 times, resulting in a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 459302.1507936
Subtracting 756 from 820 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
The number 126 fits into 640 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 459302.15079365
Subtract 630 from 640 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 459302.15079365 with a balance of 1e-08.
