We're dividing 17051312 by 620 
The aim is to understand the frequency of 620 in 17051312.

Let's proceed to step 1:
When dividing 1 by 620, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 620

Moving on to step 2:
620 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 620

Moving on to step 3:
170 divided by 620 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 170, we get 170.
Include the next digit (5) from the dividend after 170, then repeat: 1705 / 620

Going ahead to step 4:
When dividing 1705 by 620, we get 2 with a remainder of 465.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1240 from 1705 and we're left with 465.
Bring next digit (1) of the dividend behind the 465 and repeat the process: 4651 / 620

Let's proceed to step 5:
620 goes into 4651 7 times with a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 4340 from 4651 and we're left with 311.
Append the next digit (3) from the dividend to 311 and continue with: 3113 / 620

Going ahead to step 6:
620 can be fit into 3113 5 times, resulting in a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 275.0
Deduct 3100 from 3113 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 620

On to step 7:
131 divided by 620 is 0 with a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 2750.0
The remainder is 131 after subtracting 0 from 131.
Grab the next digit (2) from the dividend, add it to 131, then carry on: 1312 / 620

Advancing to step 8:
1312 divided by 620 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 27502.0
If we take 1240 away from 1312, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
The number 620 fits into 720 1 times, leaving a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 27502.1
The remainder is 100 after subtracting 620 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
When dividing 1000 by 620, we get 1 with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 27502.11
The remainder is 380 after subtracting 620 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 27502.11, with a leftover of 0.38.
