64275713 ÷ 403 
The aim is to understand the frequency of 403 in 64275713.

Going ahead to step 1:
403 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 403

On to step 2:
If we divide 64 by 403, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 403

Let's proceed to step 3:
642 divided by 403 is 1 with a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 403 from 642 leaves us with 239.
Bring next digit (7) of the dividend behind the 239 and repeat the process: 2397 / 403

Step 4:
The number 403 fits into 2397 5 times, leaving a remainder of 382.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 2015 from 2397 to get 382.
Append the next digit (5) from the dividend to 382 and continue with: 3825 / 403

Moving on to step 5:
403 goes into 3825 9 times with a remainder of 198.
Write down 9 as next digit of the result. 
Result so far: 159.0
If we subtract 3627 from 3825, we get 198.
Take the next digit (7) from the dividend and append it to 198, then repeat: 1987 / 403

Advancing to step 6:
If we divide 1987 by 403, we get 4 and a remainder of 375.
The number 4 becomes the next digit in our result. 
Result so far: 1594.0
If we subtract 1612 from 1987, we get 375.
Append the next digit (1) from the dividend to 375 and continue with: 3751 / 403

Advancing to step 7:
403 can be fit into 3751 9 times, resulting in a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 15949.0
Subtract 3627 from 3751 to get 124.
Grab the next digit (3) from the dividend, add it to 124, then carry on: 1243 / 403

On to step 8:
If we divide 1243 by 403, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 159493.0
Deduct 1209 from 1243 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 403, we get 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 159493.0
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
3400 divided by 403 is 8 with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 159493.08
If we subtract 3224 from 3400, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
The number 403 fits into 1760 4 times, leaving a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 159493.084
The remainder is 148 after subtracting 1612 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 12:
403 can be fit into 1480 3 times, resulting in a remainder of 271.
The number 3 becomes the next digit in our result. 
Result so far: 159493.0843
If we subtract 1209 from 1480, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 13:
When dividing 2710 by 403, we get 6 with a remainder of 292.
Put 6 as the next digit of the answer. 
Result so far: 159493.08436
Subtracting 2418 from 2710 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 14:
When dividing 2920 by 403, we get 7 with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 159493.084367
Subtracting 2821 from 2920 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 15:
When dividing 990 by 403, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 159493.0843672
Subtract 806 from 990 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
1840 divided by 403 is 4 with a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 159493.08436724
Subtracting 1612 from 1840 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final outcome is 159493.08436724, with a leftover of 2.28e-07.
