78791373 ÷ 939 
The aim is to understand the frequency of 939 in 78791373.

Going ahead to step 1:
939 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 939

Let's proceed to step 2:
If we divide 78 by 939, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 939

On to step 3:
If we divide 787 by 939, we get 0 and a remainder of 787.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 787 and we're left with 787.
Include the next digit (9) from the dividend after 787, then repeat: 7879 / 939

Let's proceed to step 4:
When dividing 7879 by 939, we get 8 with a remainder of 367.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 367 after subtracting 7512 from 7879.
Take the next digit (1) from the dividend and append it to 367, then repeat: 3671 / 939

On to step 5:
If we divide 3671 by 939, we get 3 and a remainder of 854.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 2817 from 3671 and we're left with 854.
Fetch the next digit (3) from the dividend, attach it to 854 and continue: 8543 / 939

Let's proceed to step 6:
If we divide 8543 by 939, we get 9 and a remainder of 92.
Use 9 as the next digit of our solution. 
Result so far: 839.0
If we take 8451 away from 8543, we end up with 92.
Grab the next digit (7) from the dividend, add it to 92, then carry on: 927 / 939

On to step 7:
The number 939 fits into 927 0 times, leaving a remainder of 927.
Use 0 as the next digit of our solution. 
Result so far: 8390.0
If we subtract 0 from 927, we get 927.
Append the next digit (3) from the dividend to 927 and continue with: 9273 / 939

On to step 8:
939 goes into 9273 9 times with a remainder of 822.
Use 9 as the next digit of our solution. 
Result so far: 83909.0
Deduct 8451 from 9273 and we're left with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Going ahead to step 9:
939 can be fit into 8220 8 times, resulting in a remainder of 708.
The next digit of our result is 8. 
Result so far: 83909.8
Subtracting 7512 from 8220 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 10:
If we divide 7080 by 939, we get 7 and a remainder of 507.
The next digit of our result is 7. 
Result so far: 83909.87
If we subtract 6573 from 7080, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 11:
If we divide 5070 by 939, we get 5 and a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 83909.875
If we take 4695 away from 5070, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 12:
The number 939 fits into 3750 3 times, leaving a remainder of 933.
Put 3 as the next digit of the answer. 
Result so far: 83909.8753
If we subtract 2817 from 3750, we get 933.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9330, and continue the process.

Advancing to step 13:
939 can be fit into 9330 9 times, resulting in a remainder of 879.
Use 9 as the next digit of our solution. 
Result so far: 83909.87539
If we subtract 8451 from 9330, we get 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Step 14:
939 goes into 8790 9 times with a remainder of 339.
The number 9 becomes the next digit in our result. 
Result so far: 83909.875399
Subtract 8451 from 8790 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Our division results in 83909.875399 with a remaining 3.39e-05.
