We look at the division of 74446302 by 388 
The aim is to understand the frequency of 388 in 74446302.

Advancing to step 1:
388 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 388

Step 2:
74 divided by 388 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 388

Step 3:
The number 388 fits into 744 1 times, leaving a remainder of 356.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 388 away from 744, we end up with 356.
Take the next digit (4) from the dividend and append it to 356, then repeat: 3564 / 388

Let's proceed to step 4:
When dividing 3564 by 388, we get 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 19.0
If we take 3492 away from 3564, we end up with 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 388

Moving on to step 5:
The number 388 fits into 726 1 times, leaving a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtract 388 from 726 to get 338.
Fetch the next digit (3) from the dividend, attach it to 338 and continue: 3383 / 388

On to step 6:
388 goes into 3383 8 times with a remainder of 279.
Put 8 as the next digit of the answer. 
Result so far: 1918.0
Subtract 3104 from 3383 to get 279.
Take the next digit (0) from the dividend and append it to 279, then repeat: 2790 / 388

Advancing to step 7:
When dividing 2790 by 388, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 19187.0
If we subtract 2716 from 2790, we get 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 388

Advancing to step 8:
742 divided by 388 is 1 with a remainder of 354.
The next digit of our result is 1. 
Result so far: 191871.0
If we take 388 away from 742, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 9:
When dividing 3540 by 388, we get 9 with a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 191871.9
Deduct 3492 from 3540 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 388, we get 1 with a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 191871.91
If we take 388 away from 480, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
388 goes into 920 2 times with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 191871.912
Subtracting 776 from 920 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 12:
If we divide 1440 by 388, we get 3 and a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 191871.9123
If we take 1164 away from 1440, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 13:
388 can be fit into 2760 7 times, resulting in a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 191871.91237
If we take 2716 away from 2760, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 388 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 191871.912371
Subtract 388 from 440 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
388 can be fit into 520 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 191871.9123711
Deduct 388 from 520 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 191871.9123711, with a leftover of 1.32e-06.
