Let's divide 11757879 by 403
The aim is to understand the frequency of 403 in 11757879.

Going ahead to step 1:
If we divide 1 by 403, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 403

On to step 2:
If we divide 11 by 403, we get 0 and a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 403

Step 3:
The number 403 fits into 117 0 times, leaving a remainder of 117.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 117 to get 117.
Take the next digit (5) from the dividend and append it to 117, then repeat: 1175 / 403

Going ahead to step 4:
If we divide 1175 by 403, we get 2 and a remainder of 369.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 806 from 1175 and we're left with 369.
Fetch the next digit (7) from the dividend, attach it to 369 and continue: 3697 / 403

Moving on to step 5:
403 goes into 3697 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtract 3627 from 3697 to get 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 403

Step 6:
403 can be fit into 708 1 times, resulting in a remainder of 305.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
If we take 403 away from 708, we end up with 305.
Append the next digit (7) from the dividend to 305 and continue with: 3057 / 403

Step 7:
403 goes into 3057 7 times with a remainder of 236.
Put 7 as the next digit of the answer. 
Result so far: 2917.0
Subtract 2821 from 3057 to get 236.
Take the next digit (9) from the dividend and append it to 236, then repeat: 2369 / 403

Moving on to step 8:
When dividing 2369 by 403, we get 5 with a remainder of 354.
Put 5 as the next digit of the answer. 
Result so far: 29175.0
If we take 2015 away from 2369, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
The number 403 fits into 3540 8 times, leaving a remainder of 316.
The next digit of our result is 8. 
Result so far: 29175.8
If we subtract 3224 from 3540, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
403 can be fit into 3160 7 times, resulting in a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 29175.87
The remainder is 339 after subtracting 2821 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 11:
When dividing 3390 by 403, we get 8 with a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 29175.878
If we take 3224 away from 3390, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 12:
When dividing 1660 by 403, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 29175.8784
Subtract 1612 from 1660 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
403 goes into 480 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 29175.87841
Subtract 403 from 480 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 14:
770 divided by 403 is 1 with a remainder of 367.
Use 1 as the next digit of our solution. 
Result so far: 29175.878411
The remainder is 367 after subtracting 403 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The final result is 29175.878411 with a remainder of 3.67e-05.
