We look at the division of 64198322 by 620 
The aim is to understand the frequency of 620 in 64198322.

Moving on to step 1:
620 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 620

On to step 2:
When dividing 64 by 620, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 620

On to step 3:
620 can be fit into 641 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 620 from 641 to get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 620

On to step 4:
If we divide 219 by 620, we get 0 and a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 219, we end up with 219.
Grab the next digit (8) from the dividend, add it to 219, then carry on: 2198 / 620

Moving on to step 5:
The number 620 fits into 2198 3 times, leaving a remainder of 338.
Put 3 as the next digit of the answer. 
Result so far: 103.0
The remainder is 338 after subtracting 1860 from 2198.
Bring next digit (3) of the dividend behind the 338 and repeat the process: 3383 / 620

Step 6:
The number 620 fits into 3383 5 times, leaving a remainder of 283.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
Subtract 3100 from 3383 to get 283.
Append the next digit (2) from the dividend to 283 and continue with: 2832 / 620

On to step 7:
620 goes into 2832 4 times with a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 10354.0
If we subtract 2480 from 2832, we get 352.
Take the next digit (2) from the dividend and append it to 352, then repeat: 3522 / 620

Going ahead to step 8:
When dividing 3522 by 620, we get 5 with a remainder of 422.
The number 5 becomes the next digit in our result. 
Result so far: 103545.0
Deduct 3100 from 3522 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 9:
The number 620 fits into 4220 6 times, leaving a remainder of 500.
Put 6 as the next digit of the answer. 
Result so far: 103545.6
Subtracting 3720 from 4220 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
5000 divided by 620 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 103545.68
The remainder is 40 after subtracting 4960 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
620 goes into 400 0 times with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 103545.68
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
620 goes into 4000 6 times with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 103545.6806
Subtract 3720 from 4000 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
2800 divided by 620 is 4 with a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 103545.68064
If we take 2480 away from 2800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
3200 divided by 620 is 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 103545.680645
Subtract 3100 from 3200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
If we divide 1000 by 620, we get 1 and a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 103545.6806451
Deduct 620 from 1000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
If we divide 3800 by 620, we get 6 and a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 103545.68064516
If we take 3720 away from 3800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 103545.68064516 with a remaining 8e-08.
