We look at the division of 42082479 by 939 
The aim is to understand the frequency of 939 in 42082479.

Going ahead to step 1:
939 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 939

Advancing to step 2:
939 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 939

Moving on to step 3:
If we divide 420 by 939, we get 0 and a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Grab the next digit (8) from the dividend, add it to 420, then carry on: 4208 / 939

Advancing to step 4:
939 can be fit into 4208 4 times, resulting in a remainder of 452.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3756 from 4208 and we're left with 452.
Bring next digit (2) of the dividend behind the 452 and repeat the process: 4522 / 939

On to step 5:
When dividing 4522 by 939, we get 4 with a remainder of 766.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 3756 from 4522, we get 766.
Grab the next digit (4) from the dividend, add it to 766, then carry on: 7664 / 939

Moving on to step 6:
939 can be fit into 7664 8 times, resulting in a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Subtract 7512 from 7664 to get 152.
Grab the next digit (7) from the dividend, add it to 152, then carry on: 1527 / 939

Moving on to step 7:
939 can be fit into 1527 1 times, resulting in a remainder of 588.
Use 1 as the next digit of our solution. 
Result so far: 4481.0
Deduct 939 from 1527 and we're left with 588.
Bring next digit (9) of the dividend behind the 588 and repeat the process: 5889 / 939

On to step 8:
939 can be fit into 5889 6 times, resulting in a remainder of 255.
The number 6 becomes the next digit in our result. 
Result so far: 44816.0
Subtract 5634 from 5889 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
2550 divided by 939 is 2 with a remainder of 672.
Put 2 as the next digit of the answer. 
Result so far: 44816.2
Subtracting 1878 from 2550 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 10:
The number 939 fits into 6720 7 times, leaving a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 44816.27
The remainder is 147 after subtracting 6573 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 11:
939 can be fit into 1470 1 times, resulting in a remainder of 531.
Use 1 as the next digit of our solution. 
Result so far: 44816.271
If we take 939 away from 1470, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Step 12:
939 goes into 5310 5 times with a remainder of 615.
Write down 5 as next digit of the result. 
Result so far: 44816.2715
The remainder is 615 after subtracting 4695 from 5310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Moving on to step 13:
If we divide 6150 by 939, we get 6 and a remainder of 516.
Use 6 as the next digit of our solution. 
Result so far: 44816.27156
Subtract 5634 from 6150 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 14:
When dividing 5160 by 939, we get 5 with a remainder of 465.
The next digit of our result is 5. 
Result so far: 44816.271565
Deduct 4695 from 5160 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 15:
4650 divided by 939 is 4 with a remainder of 894.
Use 4 as the next digit of our solution. 
Result so far: 44816.2715654
If we subtract 3756 from 4650, we get 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Advancing to step 16:
8940 divided by 939 is 9 with a remainder of 489.
Put 9 as the next digit of the answer. 
Result so far: 44816.27156549
If we subtract 8451 from 8940, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

The final result is 44816.27156549 with a remainder of 4.89e-07.
