We look at the division of 2197900 by 753 
The aim is to understand the frequency of 753 in 2197900.

On to step 1:
753 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 753

On to step 2:
When dividing 21 by 753, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 753

On to step 3:
753 can be fit into 219 0 times, resulting in a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Fetch the next digit (7) from the dividend, attach it to 219 and continue: 2197 / 753

Step 4:
If we divide 2197 by 753, we get 2 and a remainder of 691.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 691 after subtracting 1506 from 2197.
Grab the next digit (9) from the dividend, add it to 691, then carry on: 6919 / 753

On to step 5:
6919 divided by 753 is 9 with a remainder of 142.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 6777 away from 6919, we end up with 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 753

Let's proceed to step 6:
When dividing 1420 by 753, we get 1 with a remainder of 667.
Record the quotient 1 as the next digit in the result. 
Result so far: 291.0
Deduct 753 from 1420 and we're left with 667.
Append the next digit (0) from the dividend to 667 and continue with: 6670 / 753

Moving on to step 7:
When dividing 6670 by 753, we get 8 with a remainder of 646.
The next digit of our result is 8. 
Result so far: 2918.0
If we subtract 6024 from 6670, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 8:
6460 divided by 753 is 8 with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 2918.8
The remainder is 436 after subtracting 6024 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 9:
753 goes into 4360 5 times with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 2918.85
If we take 3765 away from 4360, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 10:
753 can be fit into 5950 7 times, resulting in a remainder of 679.
Write down 7 as next digit of the result. 
Result so far: 2918.857
If we subtract 5271 from 5950, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

On to step 11:
If we divide 6790 by 753, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 2918.8579
Subtracting 6777 from 6790 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
753 goes into 130 0 times with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 2918.8579
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
If we divide 1300 by 753, we get 1 and a remainder of 547.
The number 1 becomes the next digit in our result. 
Result so far: 2918.857901
Subtracting 753 from 1300 leaves us with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Let's proceed to step 14:
753 goes into 5470 7 times with a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 2918.8579017
Deduct 5271 from 5470 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 15:
When dividing 1990 by 753, we get 2 with a remainder of 484.
Put 2 as the next digit of the answer. 
Result so far: 2918.85790172
Subtracting 1506 from 1990 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

The final result is 2918.85790172 with a remainder of 4.84e-07.
