We look at the division of 26951629 by 403 
The aim is to understand the frequency of 403 in 26951629.

Let's proceed to step 1:
The number 403 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 403

Let's proceed to step 2:
When dividing 26 by 403, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 403

On to step 3:
If we divide 269 by 403, we get 0 and a remainder of 269.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 269, we end up with 269.
Take the next digit (5) from the dividend and append it to 269, then repeat: 2695 / 403

Step 4:
When dividing 2695 by 403, we get 6 with a remainder of 277.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 277 after subtracting 2418 from 2695.
Fetch the next digit (1) from the dividend, attach it to 277 and continue: 2771 / 403

Advancing to step 5:
When dividing 2771 by 403, we get 6 with a remainder of 353.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 2418 from 2771 and we're left with 353.
Grab the next digit (6) from the dividend, add it to 353, then carry on: 3536 / 403

Step 6:
If we divide 3536 by 403, we get 8 and a remainder of 312.
The next digit of our result is 8. 
Result so far: 668.0
If we subtract 3224 from 3536, we get 312.
Take the next digit (2) from the dividend and append it to 312, then repeat: 3122 / 403

Step 7:
403 goes into 3122 7 times with a remainder of 301.
Put 7 as the next digit of the answer. 
Result so far: 6687.0
Deduct 2821 from 3122 and we're left with 301.
Grab the next digit (9) from the dividend, add it to 301, then carry on: 3019 / 403

Moving on to step 8:
403 goes into 3019 7 times with a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 66877.0
If we subtract 2821 from 3019, we 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.

Step 9:
When dividing 1980 by 403, we get 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 66877.4
If we subtract 1612 from 1980, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 10:
403 can be fit into 3680 9 times, resulting in a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 66877.49
Subtracting 3627 from 3680 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 11:
403 can be fit into 530 1 times, resulting in a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 66877.491
Subtracting 403 from 530 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 12:
If we divide 1270 by 403, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 66877.4913
Subtract 1209 from 1270 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
403 goes into 610 1 times with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 66877.49131
Subtracting 403 from 610 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 14:
The number 403 fits into 2070 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 66877.491315
If we take 2015 away from 2070, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 15:
550 divided by 403 is 1 with a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 66877.4913151
The remainder is 147 after subtracting 403 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 16:
If we divide 1470 by 403, we get 3 and a remainder of 261.
Write down 3 as next digit of the result. 
Result so far: 66877.49131513
Deduct 1209 from 1470 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Our division results in 66877.49131513 with a remaining 2.61e-07.
