We look at the division of 601670 by 53 
The aim is to understand the frequency of 53 in 601670.

Step 1:
When dividing 6 by 53, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 53

Going ahead to step 2:
The number 53 fits into 60 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 53 away from 60, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 53

Going ahead to step 3:
71 divided by 53 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 53 from 71 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 53

Going ahead to step 4:
When dividing 186 by 53, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we take 159 away from 186, we end up with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 53

On to step 5:
53 goes into 277 5 times with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 1135.0
The remainder is 12 after subtracting 265 from 277.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 53

Moving on to step 6:
When dividing 120 by 53, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 11352.0
Subtract 106 from 120 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 53 is 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 11352.2
Deduct 106 from 140 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 53 fits into 340 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 11352.26
If we take 318 away from 340, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 53, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 11352.264
Subtracting 212 from 220 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
53 can be fit into 80 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11352.2641
Subtract 53 from 80 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
When dividing 270 by 53, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11352.26415
If we subtract 265 from 270, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
The number 53 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11352.26415
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
53 can be fit into 500 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 11352.2641509
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
When dividing 230 by 53, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 11352.26415094
Subtract 212 from 230 to 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.

After the division, we end up with 11352.26415094 and a remainder of 1.8e-08.
