We divide 143097 by 53
The aim is to understand the frequency of 53 in 143097.

Step 1:
53 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 53

Step 2:
53 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 53

On to step 3:
The number 53 fits into 143 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 106 from 143 leaves us with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 53

Moving on to step 4:
53 goes into 370 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 52 after subtracting 318 from 370.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 53

Moving on to step 5:
The number 53 fits into 529 9 times, leaving a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 269.0
Subtracting 477 from 529 leaves us with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 53

Moving on to step 6:
53 can be fit into 527 9 times, resulting in a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 2699.0
Deduct 477 from 527 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
When dividing 500 by 53, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 2699.9
If we take 477 away from 500, we end up 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.

Advancing to step 8:
230 divided by 53 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 2699.94
If we subtract 212 from 230, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
If we divide 180 by 53, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2699.943
If we take 159 away from 180, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
When dividing 210 by 53, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 2699.9433
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 2699.9433 and a remainder of 0.00051.
