We look at the division of 374157 by 53 
The aim is to understand the frequency of 53 in 374157.

Let's proceed to step 1:
When dividing 3 by 53, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 53

Advancing to step 2:
The number 53 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 53

On to step 3:
When dividing 374 by 53, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 371 from 374 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 53

Advancing to step 4:
31 divided by 53 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 53

Step 5:
The number 53 fits into 315 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
Deduct 265 from 315 and we're left with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 53

Going ahead to step 6:
53 goes into 507 9 times with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 7059.0
If we take 477 away from 507, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
The number 53 fits into 300 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7059.5
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 53 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7059.56
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
53 can be fit into 320 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 7059.566
If we subtract 318 from 320, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 7059.566 and a remainder of 0.0002.
