We're dividing 85554557 by 286 
The aim is to understand the frequency of 286 in 85554557.

On to step 1:
If we divide 8 by 286, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 286

Advancing to step 2:
286 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 286

Going ahead to step 3:
The number 286 fits into 855 2 times, leaving a remainder of 283.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 572 from 855 leaves us with 283.
Fetch the next digit (5) from the dividend, attach it to 283 and continue: 2835 / 286

Step 4:
The number 286 fits into 2835 9 times, leaving a remainder of 261.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 2574 from 2835 and we're left with 261.
Bring next digit (4) of the dividend behind the 261 and repeat the process: 2614 / 286

Let's proceed to step 5:
2614 divided by 286 is 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 299.0
If we take 2574 away from 2614, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 286

Moving on to step 6:
286 goes into 405 1 times with a remainder of 119.
The next digit of our result is 1. 
Result so far: 2991.0
Subtract 286 from 405 to get 119.
Bring next digit (5) of the dividend behind the 119 and repeat the process: 1195 / 286

Step 7:
1195 divided by 286 is 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 29914.0
Subtract 1144 from 1195 to get 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 286

Step 8:
The number 286 fits into 517 1 times, leaving a remainder of 231.
The next digit of our result is 1. 
Result so far: 299141.0
Subtract 286 from 517 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 9:
286 can be fit into 2310 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 299141.8
If we take 2288 away from 2310, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
286 goes into 220 0 times with a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 299141.8
If we subtract 0 from 220, 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.

On to step 11:
The number 286 fits into 2200 7 times, leaving a remainder of 198.
The next digit of our result is 7. 
Result so far: 299141.807
Subtracting 2002 from 2200 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 12:
If we divide 1980 by 286, we get 6 and a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 299141.8076
If we take 1716 away from 1980, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 13:
The number 286 fits into 2640 9 times, leaving a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 299141.80769
Subtracting 2574 from 2640 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
286 can be fit into 660 2 times, resulting in a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 299141.807692
If we take 572 away from 660, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 15:
286 goes into 880 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 299141.8076923
If we take 858 away from 880, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 16:
286 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 299141.8076923
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 299141.8076923, with a leftover of 2.2e-07.
