Let's divide 40081193 by 939
The aim is to understand the frequency of 939 in 40081193.

Going ahead to step 1:
When dividing 4 by 939, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 939

Step 2:
939 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 939

Going ahead to step 3:
If we divide 400 by 939, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 400, we get 400.
Fetch the next digit (8) from the dividend, attach it to 400 and continue: 4008 / 939

Let's proceed to step 4:
939 goes into 4008 4 times with a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3756 from 4008 leaves us with 252.
Bring next digit (1) of the dividend behind the 252 and repeat the process: 2521 / 939

Moving on to step 5:
939 can be fit into 2521 2 times, resulting in a remainder of 643.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1878 from 2521, we get 643.
Append the next digit (1) from the dividend to 643 and continue with: 6431 / 939

Let's proceed to step 6:
939 goes into 6431 6 times with a remainder of 797.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Subtracting 5634 from 6431 leaves us with 797.
Bring next digit (9) of the dividend behind the 797 and repeat the process: 7979 / 939

Moving on to step 7:
When dividing 7979 by 939, we get 8 with a remainder of 467.
The number 8 becomes the next digit in our result. 
Result so far: 4268.0
Subtract 7512 from 7979 to get 467.
Grab the next digit (3) from the dividend, add it to 467, then carry on: 4673 / 939

Moving on to step 8:
939 can be fit into 4673 4 times, resulting in a remainder of 917.
Record the quotient 4 as the next digit in the result. 
Result so far: 42684.0
Deduct 3756 from 4673 and we're left with 917.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9170, and continue the process.

Going ahead to step 9:
When dividing 9170 by 939, we get 9 with a remainder of 719.
The next digit of our result is 9. 
Result so far: 42684.9
Deduct 8451 from 9170 and we're left with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Advancing to step 10:
939 goes into 7190 7 times with a remainder of 617.
The next digit of our result is 7. 
Result so far: 42684.97
Subtract 6573 from 7190 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 11:
939 goes into 6170 6 times with a remainder of 536.
Put 6 as the next digit of the answer. 
Result so far: 42684.976
Deduct 5634 from 6170 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 12:
939 can be fit into 5360 5 times, resulting in a remainder of 665.
Record the quotient 5 as the next digit in the result. 
Result so far: 42684.9765
Subtracting 4695 from 5360 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 13:
When dividing 6650 by 939, we get 7 with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 42684.97657
Subtract 6573 from 6650 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 14:
939 can be fit into 770 0 times, resulting in a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 42684.97657
If we subtract 0 from 770, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 15:
If we divide 7700 by 939, we get 8 and a remainder of 188.
Put 8 as the next digit of the answer. 
Result so far: 42684.9765708
If we take 7512 away from 7700, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 16:
939 goes into 1880 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 42684.97657082
If we take 1878 away from 1880, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 42684.97657082 with a balance of 2e-09.
