We divide 28351890 by 626
The aim is to understand the frequency of 626 in 28351890.

Step 1:
When dividing 2 by 626, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 626

Let's proceed to step 2:
626 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 626

On to step 3:
283 divided by 626 is 0 with a remainder of 283.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 283 after subtracting 0 from 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 626

Advancing to step 4:
626 goes into 2835 4 times with a remainder of 331.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 331 after subtracting 2504 from 2835.
Grab the next digit (1) from the dividend, add it to 331, then carry on: 3311 / 626

Step 5:
3311 divided by 626 is 5 with a remainder of 181.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 3130 away from 3311, we end up with 181.
Take the next digit (8) from the dividend and append it to 181, then repeat: 1818 / 626

Step 6:
If we divide 1818 by 626, we get 2 and a remainder of 566.
Record the quotient 2 as the next digit in the result. 
Result so far: 452.0
If we subtract 1252 from 1818, we get 566.
Grab the next digit (9) from the dividend, add it to 566, then carry on: 5669 / 626

Let's proceed to step 7:
5669 divided by 626 is 9 with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 4529.0
If we subtract 5634 from 5669, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 626

Moving on to step 8:
626 goes into 350 0 times with a remainder of 350.
The next digit of our result is 0. 
Result so far: 45290.0
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
626 can be fit into 3500 5 times, resulting in a remainder of 370.
The next digit of our result is 5. 
Result so far: 45290.5
If we subtract 3130 from 3500, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
3700 divided by 626 is 5 with a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 45290.55
If we subtract 3130 from 3700, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final outcome is 45290.55, with a leftover of 0.57.
