Let's divide 19853736 by 397
The aim is to understand the frequency of 397 in 19853736.

Going ahead to step 1:
When dividing 1 by 397, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 397

Going ahead to step 2:
If we divide 19 by 397, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 397

Moving on to step 3:
The number 397 fits into 198 0 times, leaving a remainder of 198.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 198, we end up with 198.
Append the next digit (5) from the dividend to 198 and continue with: 1985 / 397

Let's proceed to step 4:
The number 397 fits into 1985 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1985 from 1985 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 397

Going ahead to step 5:
397 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 397

On to step 6:
When dividing 37 by 397, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 500.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 397

Advancing to step 7:
When dividing 373 by 397, we get 0 with a remainder of 373.
Put 0 as the next digit of the answer. 
Result so far: 5000.0
If we take 0 away from 373, we end up with 373.
Bring next digit (6) of the dividend behind the 373 and repeat the process: 3736 / 397

Step 8:
3736 divided by 397 is 9 with a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 50009.0
If we subtract 3573 from 3736, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 9:
397 can be fit into 1630 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 50009.4
Subtracting 1588 from 1630 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
The number 397 fits into 420 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 50009.41
Subtracting 397 from 420 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
230 divided by 397 is 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 50009.41
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 12:
2300 divided by 397 is 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 50009.4105
Subtract 1985 from 2300 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 13:
When dividing 3150 by 397, we get 7 with a remainder of 371.
Use 7 as the next digit of our solution. 
Result so far: 50009.41057
If we take 2779 away from 3150, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 14:
3710 divided by 397 is 9 with a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 50009.410579
Subtracting 3573 from 3710 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 15:
If we divide 1370 by 397, we get 3 and a remainder of 179.
Put 3 as the next digit of the answer. 
Result so far: 50009.4105793
Subtracting 1191 from 1370 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 16:
1790 divided by 397 is 4 with a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 50009.41057934
If we take 1588 away from 1790, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The quotient of the division is 50009.41057934, and the remainder is 2.02e-07.
