45492886 ÷ 423 
We want to figure out the number of times 45492886 can be divided by 423.

Advancing to step 1:
The number 423 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 423

Going ahead to step 2:
If we divide 45 by 423, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 423

Going ahead to step 3:
The number 423 fits into 454 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 423 from 454 to get 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 423

Advancing to step 4:
When dividing 319 by 423, we get 0 with a remainder of 319.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 319 after subtracting 0 from 319.
Fetch the next digit (2) from the dividend, attach it to 319 and continue: 3192 / 423

Moving on to step 5:
423 can be fit into 3192 7 times, resulting in a remainder of 231.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 2961 from 3192 to get 231.
Bring next digit (8) of the dividend behind the 231 and repeat the process: 2318 / 423

On to step 6:
423 can be fit into 2318 5 times, resulting in a remainder of 203.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
Deduct 2115 from 2318 and we're left with 203.
Include the next digit (8) from the dividend after 203, then repeat: 2038 / 423

Going ahead to step 7:
The number 423 fits into 2038 4 times, leaving a remainder of 346.
The next digit of our result is 4. 
Result so far: 10754.0
Deduct 1692 from 2038 and we're left with 346.
Bring next digit (6) of the dividend behind the 346 and repeat the process: 3466 / 423

Let's proceed to step 8:
The number 423 fits into 3466 8 times, leaving a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 107548.0
Deduct 3384 from 3466 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
When dividing 820 by 423, we get 1 with a remainder of 397.
Put 1 as the next digit of the answer. 
Result so far: 107548.1
Subtract 423 from 820 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 10:
If we divide 3970 by 423, we get 9 and a remainder of 163.
The number 9 becomes the next digit in our result. 
Result so far: 107548.19
Subtracting 3807 from 3970 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 11:
If we divide 1630 by 423, we get 3 and a remainder of 361.
The number 3 becomes the next digit in our result. 
Result so far: 107548.193
If we take 1269 away from 1630, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 12:
If we divide 3610 by 423, we get 8 and a remainder of 226.
The next digit of our result is 8. 
Result so far: 107548.1938
Subtracting 3384 from 3610 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 13:
423 can be fit into 2260 5 times, resulting in a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 107548.19385
Subtract 2115 from 2260 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 14:
1450 divided by 423 is 3 with a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 107548.193853
Subtract 1269 from 1450 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 15:
423 can be fit into 1810 4 times, resulting in a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 107548.1938534
The remainder is 118 after subtracting 1692 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 16:
The number 423 fits into 1180 2 times, leaving a remainder of 334.
The next digit of our result is 2. 
Result so far: 107548.19385342
Deduct 846 from 1180 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 107548.19385342 with a remainder of 3.34e-07.
