We divide 1218594 by 403
The aim is to understand the frequency of 403 in 1218594.

Advancing to step 1:
403 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 403

Going ahead to step 2:
If we divide 12 by 403, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 403

On to step 3:
When dividing 121 by 403, we get 0 with a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 121, we end up with 121.
Grab the next digit (8) from the dividend, add it to 121, then carry on: 1218 / 403

Going ahead to step 4:
403 goes into 1218 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1209 from 1218 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 403

Step 5:
When dividing 95 by 403, we get 0 with a remainder of 95.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 95, we end up with 95.
Grab the next digit (9) from the dividend, add it to 95, then carry on: 959 / 403

Going ahead to step 6:
959 divided by 403 is 2 with a remainder of 153.
The next digit of our result is 2. 
Result so far: 302.0
Subtracting 806 from 959 leaves us with 153.
Append the next digit (4) from the dividend to 153 and continue with: 1534 / 403

Step 7:
When dividing 1534 by 403, we get 3 with a remainder of 325.
Put 3 as the next digit of the answer. 
Result so far: 3023.0
Deduct 1209 from 1534 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 8:
When dividing 3250 by 403, we get 8 with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 3023.8
Subtracting 3224 from 3250 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
If we divide 260 by 403, we get 0 and a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 3023.8
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
403 goes into 2600 6 times with a remainder of 182.
The next digit of our result is 6. 
Result so far: 3023.806
Subtract 2418 from 2600 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 11:
403 can be fit into 1820 4 times, resulting in a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 3023.8064
If we take 1612 away from 1820, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
When dividing 2080 by 403, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 3023.80645
Subtract 2015 from 2080 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
403 can be fit into 650 1 times, resulting in a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 3023.806451
Deduct 403 from 650 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 14:
If we divide 2470 by 403, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 3023.8064516
If we subtract 2418 from 2470, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 15:
403 can be fit into 520 1 times, resulting in a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 3023.80645161
If we take 403 away from 520, we end up 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.

In conclusion, the division gives 3023.80645161 with a balance of 1.17e-07.
