We look at the division of 53182221 by 380 
The aim is to understand the frequency of 380 in 53182221.

Step 1:
If we divide 5 by 380, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 380

Moving on to step 2:
380 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 380

Let's proceed to step 3:
When dividing 531 by 380, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 380 from 531 leaves us with 151.
Append the next digit (8) from the dividend to 151 and continue with: 1518 / 380

Let's proceed to step 4:
380 can be fit into 1518 3 times, resulting in a remainder of 378.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1140 from 1518, we get 378.
Take the next digit (2) from the dividend and append it to 378, then repeat: 3782 / 380

Step 5:
380 can be fit into 3782 9 times, resulting in a remainder of 362.
The next digit of our result is 9. 
Result so far: 139.0
If we subtract 3420 from 3782, we get 362.
Include the next digit (2) from the dividend after 362, then repeat: 3622 / 380

Moving on to step 6:
380 can be fit into 3622 9 times, resulting in a remainder of 202.
Record the quotient 9 as the next digit in the result. 
Result so far: 1399.0
The remainder is 202 after subtracting 3420 from 3622.
Bring next digit (2) of the dividend behind the 202 and repeat the process: 2022 / 380

Step 7:
If we divide 2022 by 380, we get 5 and a remainder of 122.
The number 5 becomes the next digit in our result. 
Result so far: 13995.0
If we subtract 1900 from 2022, we get 122.
Include the next digit (1) from the dividend after 122, then repeat: 1221 / 380

Advancing to step 8:
The number 380 fits into 1221 3 times, leaving a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 139953.0
Deduct 1140 from 1221 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
380 goes into 810 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 139953.2
Subtract 760 from 810 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
380 goes into 500 1 times with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 139953.21
Subtract 380 from 500 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
The number 380 fits into 1200 3 times, leaving a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 139953.213
If we take 1140 away from 1200, 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.

On to step 12:
600 divided by 380 is 1 with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 139953.2131
If we subtract 380 from 600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 13:
When dividing 2200 by 380, we get 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 139953.21315
Deduct 1900 from 2200 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
380 goes into 3000 7 times with a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 139953.213157
Deduct 2660 from 3000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
380 goes into 3400 8 times with a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 139953.2131578
Subtracting 3040 from 3400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 16:
If we divide 3600 by 380, we get 9 and a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 139953.21315789
Subtract 3420 from 3600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 139953.21315789 with a remaining 1.8e-07.
