We divide 37980201 by 381
The aim is to understand the frequency of 381 in 37980201.

Let's proceed to step 1:
The number 381 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 381

Step 2:
If we divide 37 by 381, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 381

Let's proceed to step 3:
381 can be fit into 379 0 times, resulting in a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Grab the next digit (8) from the dividend, add it to 379, then carry on: 3798 / 381

Moving on to step 4:
If we divide 3798 by 381, we get 9 and a remainder of 369.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 3429 from 3798 leaves us with 369.
Fetch the next digit (0) from the dividend, attach it to 369 and continue: 3690 / 381

On to step 5:
381 goes into 3690 9 times with a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 3429 from 3690, we get 261.
Grab the next digit (2) from the dividend, add it to 261, then carry on: 2612 / 381

Going ahead to step 6:
When dividing 2612 by 381, we get 6 with a remainder of 326.
The next digit of our result is 6. 
Result so far: 996.0
If we subtract 2286 from 2612, we get 326.
Grab the next digit (0) from the dividend, add it to 326, then carry on: 3260 / 381

Step 7:
The number 381 fits into 3260 8 times, leaving a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 9968.0
If we subtract 3048 from 3260, we get 212.
Include the next digit (1) from the dividend after 212, then repeat: 2121 / 381

Step 8:
If we divide 2121 by 381, we get 5 and a remainder of 216.
Write down 5 as next digit of the result. 
Result so far: 99685.0
Subtract 1905 from 2121 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 9:
The number 381 fits into 2160 5 times, leaving a remainder of 255.
The next digit of our result is 5. 
Result so far: 99685.5
If we subtract 1905 from 2160, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 10:
2550 divided by 381 is 6 with a remainder of 264.
The next digit of our result is 6. 
Result so far: 99685.56
Deduct 2286 from 2550 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 11:
If we divide 2640 by 381, we get 6 and a remainder of 354.
Write down 6 as next digit of the result. 
Result so far: 99685.566
Deduct 2286 from 2640 and we're left 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.

The final result is 99685.566 with a remainder of 0.0354.
