We divide 71023625 by 286
The aim is to understand the frequency of 286 in 71023625.

Moving on to step 1:
When dividing 7 by 286, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 286

Advancing to step 2:
When dividing 71 by 286, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 286

Going ahead to step 3:
286 can be fit into 710 2 times, resulting in a remainder of 138.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 572 from 710 and we're left with 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 286

Going ahead to step 4:
286 can be fit into 1382 4 times, resulting in a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 1144 away from 1382, we end up with 238.
Take the next digit (3) from the dividend and append it to 238, then repeat: 2383 / 286

Going ahead to step 5:
When dividing 2383 by 286, we get 8 with a remainder of 95.
The next digit of our result is 8. 
Result so far: 248.0
Deduct 2288 from 2383 and we're left with 95.
Append the next digit (6) from the dividend to 95 and continue with: 956 / 286

Going ahead to step 6:
956 divided by 286 is 3 with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 2483.0
If we take 858 away from 956, we end up with 98.
Take the next digit (2) from the dividend and append it to 98, then repeat: 982 / 286

Going ahead to step 7:
If we divide 982 by 286, we get 3 and a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 24833.0
The remainder is 124 after subtracting 858 from 982.
Include the next digit (5) from the dividend after 124, then repeat: 1245 / 286

Step 8:
When dividing 1245 by 286, we get 4 with a remainder of 101.
Put 4 as the next digit of the answer. 
Result so far: 248334.0
If we take 1144 away from 1245, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
If we divide 1010 by 286, we get 3 and a remainder of 152.
The number 3 becomes the next digit in our result. 
Result so far: 248334.3
If we subtract 858 from 1010, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
286 goes into 1520 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 248334.35
Subtracting 1430 from 1520 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
286 can be fit into 900 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 248334.353
Deduct 858 from 900 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
When dividing 420 by 286, we get 1 with a remainder of 134.
The next digit of our result is 1. 
Result so far: 248334.3531
Deduct 286 from 420 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 13:
1340 divided by 286 is 4 with a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 248334.35314
If we take 1144 away from 1340, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 14:
286 goes into 1960 6 times with a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 248334.353146
Subtract 1716 from 1960 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 15:
When dividing 2440 by 286, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 248334.3531468
Subtract 2288 from 2440 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 16:
1520 divided by 286 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 248334.35314685
If we subtract 1430 from 1520, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 248334.35314685 and a remainder of 9e-08.
