We divide 77666592 by 620
The aim is to understand the frequency of 620 in 77666592.

Going ahead to step 1:
7 divided by 620 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 620

Moving on to step 2:
620 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 620

Going ahead to step 3:
776 divided by 620 is 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 620 away from 776, we end up with 156.
Append the next digit (6) from the dividend to 156 and continue with: 1566 / 620

Advancing to step 4:
1566 divided by 620 is 2 with a remainder of 326.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1240 away from 1566, we end up with 326.
Fetch the next digit (6) from the dividend, attach it to 326 and continue: 3266 / 620

Moving on to step 5:
620 goes into 3266 5 times with a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we take 3100 away from 3266, we end up with 166.
Take the next digit (5) from the dividend and append it to 166, then repeat: 1665 / 620

On to step 6:
If we divide 1665 by 620, we get 2 and a remainder of 425.
Record the quotient 2 as the next digit in the result. 
Result so far: 1252.0
If we subtract 1240 from 1665, we get 425.
Grab the next digit (9) from the dividend, add it to 425, then carry on: 4259 / 620

On to step 7:
620 goes into 4259 6 times with a remainder of 539.
Use 6 as the next digit of our solution. 
Result so far: 12526.0
If we take 3720 away from 4259, we end up with 539.
Take the next digit (2) from the dividend and append it to 539, then repeat: 5392 / 620

Step 8:
620 can be fit into 5392 8 times, resulting in a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 125268.0
If we take 4960 away from 5392, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 9:
620 goes into 4320 6 times with a remainder of 600.
The next digit of our result is 6. 
Result so far: 125268.6
If we take 3720 away from 4320, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 10:
620 goes into 6000 9 times with a remainder of 420.
The next digit of our result is 9. 
Result so far: 125268.69
Subtract 5580 from 6000 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
4200 divided by 620 is 6 with a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 125268.696
Subtracting 3720 from 4200 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
4800 divided by 620 is 7 with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 125268.6967
Deduct 4340 from 4800 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 13:
When dividing 4600 by 620, we get 7 with a remainder of 260.
Use 7 as the next digit of our solution. 
Result so far: 125268.69677
Subtracting 4340 from 4600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 125268.69677, and the remainder is 0.00026.
