71525520 divided by 388 
The aim is to understand the frequency of 388 in 71525520.

Advancing to step 1:
The number 388 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 388

Step 2:
The number 388 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 388

Moving on to step 3:
When dividing 715 by 388, we get 1 with a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 327 after subtracting 388 from 715.
Append the next digit (2) from the dividend to 327 and continue with: 3272 / 388

On to step 4:
3272 divided by 388 is 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 3104 from 3272 and we're left with 168.
Take the next digit (5) from the dividend and append it to 168, then repeat: 1685 / 388

On to step 5:
388 goes into 1685 4 times with a remainder of 133.
The next digit of our result is 4. 
Result so far: 184.0
Subtracting 1552 from 1685 leaves us with 133.
Include the next digit (5) from the dividend after 133, then repeat: 1335 / 388

Moving on to step 6:
If we divide 1335 by 388, we get 3 and a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 1843.0
Subtracting 1164 from 1335 leaves us with 171.
Fetch the next digit (2) from the dividend, attach it to 171 and continue: 1712 / 388

Going ahead to step 7:
388 can be fit into 1712 4 times, resulting in a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 18434.0
Deduct 1552 from 1712 and we're left with 160.
Include the next digit (0) from the dividend after 160, then repeat: 1600 / 388

Advancing to step 8:
388 can be fit into 1600 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 184344.0
The remainder is 48 after subtracting 1552 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 388 is 1 with a remainder of 92.
Put 1 as the next digit of the answer. 
Result so far: 184344.1
If we subtract 388 from 480, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 10:
388 can be fit into 920 2 times, resulting in a remainder of 144.
The next digit of our result is 2. 
Result so far: 184344.12
If we subtract 776 from 920, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
1440 divided by 388 is 3 with a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 184344.123
Deduct 1164 from 1440 and we're left 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 12:
The number 388 fits into 2760 7 times, leaving a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 184344.1237
Subtracting 2716 from 2760 leaves us 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.

Moving on to step 13:
The number 388 fits into 440 1 times, leaving a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 184344.12371
Deduct 388 from 440 and we're left with 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 14:
When dividing 520 by 388, we get 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 184344.123711
If we take 388 away from 520, we end up 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 184344.123711, with a leftover of 1.32e-05.
