Let's divide 18661641 by 403
We want to figure out the number of times 18661641 can be divided by 403.

Moving on to step 1:
403 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 403

Going ahead to step 2:
The number 403 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 403

On to step 3:
403 can be fit into 186 0 times, resulting in a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 186 leaves us with 186.
Take the next digit (6) from the dividend and append it to 186, then repeat: 1866 / 403

Let's proceed to step 4:
The number 403 fits into 1866 4 times, leaving a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1612 from 1866, we get 254.
Include the next digit (1) from the dividend after 254, then repeat: 2541 / 403

Advancing to step 5:
If we divide 2541 by 403, we get 6 and a remainder of 123.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 2418 away from 2541, we end up with 123.
Append the next digit (6) from the dividend to 123 and continue with: 1236 / 403

Moving on to step 6:
When dividing 1236 by 403, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 463.0
If we take 1209 away from 1236, we end up with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 403

On to step 7:
If we divide 274 by 403, we get 0 and a remainder of 274.
Record the quotient 0 as the next digit in the result. 
Result so far: 4630.0
If we take 0 away from 274, we end up with 274.
Grab the next digit (1) from the dividend, add it to 274, then carry on: 2741 / 403

On to step 8:
2741 divided by 403 is 6 with a remainder of 323.
Write down 6 as next digit of the result. 
Result so far: 46306.0
Deduct 2418 from 2741 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 9:
The number 403 fits into 3230 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 46306.8
Deduct 3224 from 3230 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 403, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 46306.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
If we divide 600 by 403, we get 1 and a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 46306.801
Deduct 403 from 600 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 12:
The number 403 fits into 1970 4 times, leaving a remainder of 358.
The number 4 becomes the next digit in our result. 
Result so far: 46306.8014
If we subtract 1612 from 1970, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
When dividing 3580 by 403, we get 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 46306.80148
If we take 3224 away from 3580, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 14:
If we divide 3560 by 403, we get 8 and a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 46306.801488
If we take 3224 away from 3560, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 46306.801488 with a remainder of 3.36e-05.
