We're dividing 6992939 by 620 
The aim is to understand the frequency of 620 in 6992939.

Let's proceed to step 1:
When dividing 6 by 620, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 620

Going ahead to step 2:
620 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 620

On to step 3:
699 divided by 620 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1.0
If we take 620 away from 699, we end up with 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 620

Moving on to step 4:
When dividing 792 by 620, we get 1 with a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 620 from 792 and we're left with 172.
Include the next digit (9) from the dividend after 172, then repeat: 1729 / 620

Going ahead to step 5:
The number 620 fits into 1729 2 times, leaving a remainder of 489.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 1240 from 1729 to get 489.
Grab the next digit (3) from the dividend, add it to 489, then carry on: 4893 / 620

Let's proceed to step 6:
4893 divided by 620 is 7 with a remainder of 553.
The number 7 becomes the next digit in our result. 
Result so far: 1127.0
If we subtract 4340 from 4893, we get 553.
Grab the next digit (9) from the dividend, add it to 553, then carry on: 5539 / 620

Moving on to step 7:
620 can be fit into 5539 8 times, resulting in a remainder of 579.
Write down 8 as next digit of the result. 
Result so far: 11278.0
If we take 4960 away from 5539, we end up with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 8:
If we divide 5790 by 620, we get 9 and a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 11278.9
The remainder is 210 after subtracting 5580 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
2100 divided by 620 is 3 with a remainder of 240.
The next digit of our result is 3. 
Result so far: 11278.93
If we subtract 1860 from 2100, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
If we divide 2400 by 620, we get 3 and a remainder of 540.
Record the quotient 3 as the next digit in the result. 
Result so far: 11278.933
If we take 1860 away from 2400, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 11278.933, with a leftover of 0.054.
