We look at the division of 37019384 by 388 
The aim is to understand the frequency of 388 in 37019384.

Going ahead to step 1:
If we divide 3 by 388, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 388

Advancing to step 2:
388 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 388

On to step 3:
388 can be fit into 370 0 times, resulting in a remainder of 370.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 370 leaves us with 370.
Include the next digit (1) from the dividend after 370, then repeat: 3701 / 388

Advancing to step 4:
3701 divided by 388 is 9 with a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 3492 from 3701 and we're left with 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 388

Advancing to step 5:
388 goes into 2099 5 times with a remainder of 159.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 1940 from 2099, we get 159.
Take the next digit (3) from the dividend and append it to 159, then repeat: 1593 / 388

Step 6:
When dividing 1593 by 388, we get 4 with a remainder of 41.
The next digit of our result is 4. 
Result so far: 954.0
If we subtract 1552 from 1593, we get 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 388

Moving on to step 7:
418 divided by 388 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 9541.0
Subtracting 388 from 418 leaves us with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 388

Advancing to step 8:
304 divided by 388 is 0 with a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 95410.0
Subtract 0 from 304 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 9:
388 can be fit into 3040 7 times, resulting in a remainder of 324.
Write down 7 as next digit of the result. 
Result so far: 95410.7
Deduct 2716 from 3040 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 10:
388 goes into 3240 8 times with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 95410.78
Deduct 3104 from 3240 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 11:
When dividing 1360 by 388, we get 3 with a remainder of 196.
Put 3 as the next digit of the answer. 
Result so far: 95410.783
If we take 1164 away from 1360, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 12:
When dividing 1960 by 388, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 95410.7835
Subtracting 1940 from 1960 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
388 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 95410.7835
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
2000 divided by 388 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 95410.783505
If we take 1940 away from 2000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
600 divided by 388 is 1 with a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 95410.7835051
The remainder is 212 after subtracting 388 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 16:
When dividing 2120 by 388, we get 5 with a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 95410.78350515
Deduct 1940 from 2120 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 95410.78350515, with a leftover of 1.8e-07.
