We divide 40072267 by 620
The aim is to understand the frequency of 620 in 40072267.

Going ahead to step 1:
When dividing 4 by 620, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 620

Advancing to step 2:
The number 620 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 620

On to step 3:
620 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 400, we get 400.
Fetch the next digit (7) from the dividend, attach it to 400 and continue: 4007 / 620

Advancing to step 4:
If we divide 4007 by 620, we get 6 and a remainder of 287.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 3720 away from 4007, we end up with 287.
Include the next digit (2) from the dividend after 287, then repeat: 2872 / 620

Moving on to step 5:
620 can be fit into 2872 4 times, resulting in a remainder of 392.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 2480 from 2872, we get 392.
Bring next digit (2) of the dividend behind the 392 and repeat the process: 3922 / 620

Going ahead to step 6:
3922 divided by 620 is 6 with a remainder of 202.
The number 6 becomes the next digit in our result. 
Result so far: 646.0
Deduct 3720 from 3922 and we're left with 202.
Append the next digit (6) from the dividend to 202 and continue with: 2026 / 620

Step 7:
The number 620 fits into 2026 3 times, leaving a remainder of 166.
The next digit of our result is 3. 
Result so far: 6463.0
If we take 1860 away from 2026, we end up with 166.
Fetch the next digit (7) from the dividend, attach it to 166 and continue: 1667 / 620

On to step 8:
When dividing 1667 by 620, we get 2 with a remainder of 427.
The number 2 becomes the next digit in our result. 
Result so far: 64632.0
Deduct 1240 from 1667 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Let's proceed to step 9:
620 goes into 4270 6 times with a remainder of 550.
The number 6 becomes the next digit in our result. 
Result so far: 64632.6
If we subtract 3720 from 4270, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 10:
5500 divided by 620 is 8 with a remainder of 540.
Use 8 as the next digit of our solution. 
Result so far: 64632.68
Subtract 4960 from 5500 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
620 can be fit into 5400 8 times, resulting in a remainder of 440.
The next digit of our result is 8. 
Result so far: 64632.688
Subtract 4960 from 5400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 64632.688, with a leftover of 0.044.
