13534219 divided by 285 
The aim is to understand the frequency of 285 in 13534219.

Going ahead to step 1:
When dividing 1 by 285, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 285

Step 2:
If we divide 13 by 285, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 285

On to step 3:
285 goes into 135 0 times with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Grab the next digit (3) from the dividend, add it to 135, then carry on: 1353 / 285

Step 4:
The number 285 fits into 1353 4 times, leaving a remainder of 213.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 213 after subtracting 1140 from 1353.
Include the next digit (4) from the dividend after 213, then repeat: 2134 / 285

Advancing to step 5:
2134 divided by 285 is 7 with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 1995 from 2134 leaves us with 139.
Bring next digit (2) of the dividend behind the 139 and repeat the process: 1392 / 285

On to step 6:
285 goes into 1392 4 times with a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
Subtract 1140 from 1392 to get 252.
Grab the next digit (1) from the dividend, add it to 252, then carry on: 2521 / 285

On to step 7:
If we divide 2521 by 285, we get 8 and a remainder of 241.
Record the quotient 8 as the next digit in the result. 
Result so far: 4748.0
Subtracting 2280 from 2521 leaves us with 241.
Include the next digit (9) from the dividend after 241, then repeat: 2419 / 285

Moving on to step 8:
285 goes into 2419 8 times with a remainder of 139.
The number 8 becomes the next digit in our result. 
Result so far: 47488.0
If we subtract 2280 from 2419, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
1390 divided by 285 is 4 with a remainder of 250.
The number 4 becomes the next digit in our result. 
Result so far: 47488.4
Deduct 1140 from 1390 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
When dividing 2500 by 285, we get 8 with a remainder of 220.
Record the quotient 8 as the next digit in the result. 
Result so far: 47488.48
If we subtract 2280 from 2500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
The number 285 fits into 2200 7 times, leaving a remainder of 205.
The next digit of our result is 7. 
Result so far: 47488.487
If we take 1995 away from 2200, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 12:
The number 285 fits into 2050 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 47488.4877
If we subtract 1995 from 2050, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 47488.4877 and a remainder of 0.00055.
