We're dividing 78629786 by 403 
The aim is to understand the frequency of 403 in 78629786.

Let's proceed to step 1:
7 divided by 403 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 403

On to step 2:
If we divide 78 by 403, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 403

On to step 3:
If we divide 786 by 403, we get 1 and a remainder of 383.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 403 from 786, we get 383.
Grab the next digit (2) from the dividend, add it to 383, then carry on: 3832 / 403

On to step 4:
403 goes into 3832 9 times with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3627 from 3832 to get 205.
Include the next digit (9) from the dividend after 205, then repeat: 2059 / 403

Let's proceed to step 5:
403 goes into 2059 5 times with a remainder of 44.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtracting 2015 from 2059 leaves us with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 403

Let's proceed to step 6:
403 goes into 447 1 times with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1951.0
If we take 403 away from 447, we end up with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 403

Let's proceed to step 7:
403 can be fit into 448 1 times, resulting in a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 19511.0
If we take 403 away from 448, we end up with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 403

Moving on to step 8:
The number 403 fits into 456 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 195111.0
Subtracting 403 from 456 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 9:
403 goes into 530 1 times with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 195111.1
If we subtract 403 from 530, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
If we divide 1270 by 403, we get 3 and a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 195111.13
The remainder is 61 after subtracting 1209 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 11:
610 divided by 403 is 1 with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 195111.131
If we take 403 away from 610, we end up 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.

Step 12:
2070 divided by 403 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 195111.1315
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.

On to step 13:
403 goes into 550 1 times with a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 195111.13151
If we take 403 away from 550, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 14:
When dividing 1470 by 403, we get 3 with a remainder of 261.
Use 3 as the next digit of our solution. 
Result so far: 195111.131513
If we take 1209 away from 1470, we end up 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.

On to step 15:
When dividing 2610 by 403, we get 6 with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 195111.1315136
If we take 2418 away from 2610, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 16:
When dividing 1920 by 403, we get 4 with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 195111.13151364
The remainder is 308 after subtracting 1612 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

After the division, we end up with 195111.13151364 and a remainder of 3.08e-07.
