We're dividing 99531582 by 209 
The aim is to understand the frequency of 209 in 99531582.

Going ahead to step 1:
If we divide 9 by 209, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 209

Advancing to step 2:
209 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 209

Advancing to step 3:
209 goes into 995 4 times with a remainder of 159.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 836 from 995 leaves us with 159.
Bring next digit (3) of the dividend behind the 159 and repeat the process: 1593 / 209

Advancing to step 4:
If we divide 1593 by 209, we get 7 and a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 1463 from 1593 leaves us with 130.
Include the next digit (1) from the dividend after 130, then repeat: 1301 / 209

Moving on to step 5:
209 goes into 1301 6 times with a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 476.0
If we take 1254 away from 1301, we end up with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 209

Advancing to step 6:
475 divided by 209 is 2 with a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 4762.0
The remainder is 57 after subtracting 418 from 475.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 209

Moving on to step 7:
578 divided by 209 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 47622.0
Deduct 418 from 578 and we're left with 160.
Fetch the next digit (2) from the dividend, attach it to 160 and continue: 1602 / 209

On to step 8:
When dividing 1602 by 209, we get 7 with a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 476227.0
The remainder is 139 after subtracting 1463 from 1602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
When dividing 1390 by 209, we get 6 with a remainder of 136.
The next digit of our result is 6. 
Result so far: 476227.6
The remainder is 136 after subtracting 1254 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
1360 divided by 209 is 6 with a remainder of 106.
The next digit of our result is 6. 
Result so far: 476227.66
Subtracting 1254 from 1360 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 476227.66, and the remainder is 0.106.
