We're dividing 23278230 by 249 
The aim is to understand the frequency of 249 in 23278230.

Going ahead to step 1:
2 divided by 249 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 249

On to step 2:
23 divided by 249 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 249

Going ahead to step 3:
The number 249 fits into 232 0 times, leaving a remainder of 232.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 232 to get 232.
Fetch the next digit (7) from the dividend, attach it to 232 and continue: 2327 / 249

Going ahead to step 4:
If we divide 2327 by 249, we get 9 and a remainder of 86.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 2241 from 2327 leaves us with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 249

Going ahead to step 5:
When dividing 868 by 249, we get 3 with a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 747 from 868 and we're left with 121.
Grab the next digit (2) from the dividend, add it to 121, then carry on: 1212 / 249

Advancing to step 6:
If we divide 1212 by 249, we get 4 and a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 934.0
Deduct 996 from 1212 and we're left with 216.
Append the next digit (3) from the dividend to 216 and continue with: 2163 / 249

On to step 7:
249 goes into 2163 8 times with a remainder of 171.
Record the quotient 8 as the next digit in the result. 
Result so far: 9348.0
If we take 1992 away from 2163, we end up with 171.
Append the next digit (0) from the dividend to 171 and continue with: 1710 / 249

Moving on to step 8:
When dividing 1710 by 249, we get 6 with a remainder of 216.
Put 6 as the next digit of the answer. 
Result so far: 93486.0
Subtracting 1494 from 1710 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 9:
249 goes into 2160 8 times with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 93486.8
Subtract 1992 from 2160 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 10:
If we divide 1680 by 249, we get 6 and a remainder of 186.
The next digit of our result is 6. 
Result so far: 93486.86
Deduct 1494 from 1680 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 11:
1860 divided by 249 is 7 with a remainder of 117.
The next digit of our result is 7. 
Result so far: 93486.867
Subtracting 1743 from 1860 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 12:
1170 divided by 249 is 4 with a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 93486.8674
If we subtract 996 from 1170, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 13:
When dividing 1740 by 249, we get 6 with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 93486.86746
If we take 1494 away from 1740, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 14:
If we divide 2460 by 249, we get 9 and a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 93486.867469
If we take 2241 away from 2460, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 15:
The number 249 fits into 2190 8 times, leaving a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 93486.8674698
Subtract 1992 from 2190 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 16:
The number 249 fits into 1980 7 times, leaving a remainder of 237.
Write down 7 as next digit of the result. 
Result so far: 93486.86746987
If we take 1743 away from 1980, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

The final result is 93486.86746987 with a remainder of 2.37e-07.
