79381534 ÷ 407 
The aim is to understand the frequency of 407 in 79381534.

Advancing to step 1:
407 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
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 407

On to step 2:
When dividing 79 by 407, we get 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 407

Advancing to step 3:
The number 407 fits into 793 1 times, leaving a remainder of 386.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 407 away from 793, we end up with 386.
Bring next digit (8) of the dividend behind the 386 and repeat the process: 3868 / 407

Let's proceed to step 4:
407 goes into 3868 9 times with a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 205 after subtracting 3663 from 3868.
Include the next digit (1) from the dividend after 205, then repeat: 2051 / 407

Step 5:
If we divide 2051 by 407, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtract 2035 from 2051 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 407

Going ahead to step 6:
407 can be fit into 165 0 times, resulting in a remainder of 165.
The number 0 becomes the next digit in our result. 
Result so far: 1950.0
The remainder is 165 after subtracting 0 from 165.
Take the next digit (3) from the dividend and append it to 165, then repeat: 1653 / 407

Let's proceed to step 7:
If we divide 1653 by 407, we get 4 and a remainder of 25.
The next digit of our result is 4. 
Result so far: 19504.0
If we take 1628 away from 1653, we end up with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 407

Going ahead to step 8:
407 goes into 254 0 times with a remainder of 254.
Use 0 as the next digit of our solution. 
Result so far: 195040.0
Subtracting 0 from 254 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 9:
407 goes into 2540 6 times with a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 195040.6
The remainder is 98 after subtracting 2442 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
When dividing 980 by 407, we get 2 with a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 195040.62
Subtract 814 from 980 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 11:
If we divide 1660 by 407, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 195040.624
If we take 1628 away from 1660, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
407 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 195040.624
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
407 can be fit into 3200 7 times, resulting in a remainder of 351.
Write down 7 as next digit of the result. 
Result so far: 195040.62407
Deduct 2849 from 3200 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 14:
3510 divided by 407 is 8 with a remainder of 254.
The next digit of our result is 8. 
Result so far: 195040.624078
Deduct 3256 from 3510 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 15:
When dividing 2540 by 407, we get 6 with a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 195040.6240786
If we subtract 2442 from 2540, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
If we divide 980 by 407, we get 2 and a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 195040.62407862
Subtracting 814 from 980 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 195040.62407862 with a remainder of 1.66e-07.
