82850753 ÷ 620 
The aim is to understand the frequency of 620 in 82850753.

Advancing to step 1:
8 divided by 620 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 620

Step 2:
If we divide 82 by 620, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 620

On to step 3:
If we divide 828 by 620, we get 1 and a remainder of 208.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 620 from 828 and we're left with 208.
Append the next digit (5) from the dividend to 208 and continue with: 2085 / 620

On to step 4:
620 can be fit into 2085 3 times, resulting in a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1860 from 2085 leaves us with 225.
Include the next digit (0) from the dividend after 225, then repeat: 2250 / 620

Moving on to step 5:
620 goes into 2250 3 times with a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we take 1860 away from 2250, we end up with 390.
Append the next digit (7) from the dividend to 390 and continue with: 3907 / 620

Let's proceed to step 6:
620 can be fit into 3907 6 times, resulting in a remainder of 187.
Record the quotient 6 as the next digit in the result. 
Result so far: 1336.0
Subtracting 3720 from 3907 leaves us with 187.
Append the next digit (5) from the dividend to 187 and continue with: 1875 / 620

Going ahead to step 7:
If we divide 1875 by 620, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 13363.0
Subtract 1860 from 1875 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 620

On to step 8:
If we divide 153 by 620, we get 0 and a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 133630.0
The remainder is 153 after subtracting 0 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 9:
620 can be fit into 1530 2 times, resulting in a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 133630.2
If we take 1240 away from 1530, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
The number 620 fits into 2900 4 times, leaving a remainder of 420.
Use 4 as the next digit of our solution. 
Result so far: 133630.24
If we take 2480 away from 2900, we end up with 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:
The number 620 fits into 4200 6 times, leaving a remainder of 480.
The next digit of our result is 6. 
Result so far: 133630.246
Subtract 3720 from 4200 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
The number 620 fits into 4800 7 times, leaving a remainder of 460.
The number 7 becomes the next digit in our result. 
Result so far: 133630.2467
The remainder is 460 after subtracting 4340 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
620 can be fit into 4600 7 times, resulting in a remainder of 260.
Use 7 as the next digit of our solution. 
Result so far: 133630.24677
Deduct 4340 from 4600 and we're left 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 final outcome is 133630.24677, with a leftover of 0.00026.
