We look at the division of 54173868 by 939 
The aim is to understand the frequency of 939 in 54173868.

Advancing to step 1:
When dividing 5 by 939, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 939

Advancing to step 2:
939 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 939

Going ahead to step 3:
939 goes into 541 0 times with a remainder of 541.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 541, we end up with 541.
Bring next digit (7) of the dividend behind the 541 and repeat the process: 5417 / 939

Let's proceed to step 4:
5417 divided by 939 is 5 with a remainder of 722.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4695 away from 5417, we end up with 722.
Take the next digit (3) from the dividend and append it to 722, then repeat: 7223 / 939

Going ahead to step 5:
If we divide 7223 by 939, we get 7 and a remainder of 650.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 650 after subtracting 6573 from 7223.
Bring next digit (8) of the dividend behind the 650 and repeat the process: 6508 / 939

Advancing to step 6:
The number 939 fits into 6508 6 times, leaving a remainder of 874.
The next digit of our result is 6. 
Result so far: 576.0
The remainder is 874 after subtracting 5634 from 6508.
Bring next digit (6) of the dividend behind the 874 and repeat the process: 8746 / 939

Advancing to step 7:
939 goes into 8746 9 times with a remainder of 295.
Write down 9 as next digit of the result. 
Result so far: 5769.0
The remainder is 295 after subtracting 8451 from 8746.
Append the next digit (8) from the dividend to 295 and continue with: 2958 / 939

On to step 8:
2958 divided by 939 is 3 with a remainder of 141.
Write down 3 as next digit of the result. 
Result so far: 57693.0
Subtract 2817 from 2958 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 9:
1410 divided by 939 is 1 with a remainder of 471.
Put 1 as the next digit of the answer. 
Result so far: 57693.1
If we subtract 939 from 1410, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 10:
939 can be fit into 4710 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 57693.15
If we subtract 4695 from 4710, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
939 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 57693.15
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
If we divide 1500 by 939, we get 1 and a remainder of 561.
The next digit of our result is 1. 
Result so far: 57693.1501
The remainder is 561 after subtracting 939 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 13:
When dividing 5610 by 939, we get 5 with a remainder of 915.
The next digit of our result is 5. 
Result so far: 57693.15015
The remainder is 915 after subtracting 4695 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

Let's proceed to step 14:
When dividing 9150 by 939, we get 9 with a remainder of 699.
Put 9 as the next digit of the answer. 
Result so far: 57693.150159
If we take 8451 away from 9150, we end up with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Let's proceed to step 15:
6990 divided by 939 is 7 with a remainder of 417.
Put 7 as the next digit of the answer. 
Result so far: 57693.1501597
If we take 6573 away from 6990, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 16:
The number 939 fits into 4170 4 times, leaving a remainder of 414.
Write down 4 as next digit of the result. 
Result so far: 57693.15015974
Subtracting 3756 from 4170 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The final result is 57693.15015974 with a remainder of 4.14e-07.
