20351123 ÷ 453 
We're looking to find how many times 453 goes into 20351123.

Advancing to step 1:
When dividing 2 by 453, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 453

Step 2:
20 divided by 453 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 453

Advancing to step 3:
If we divide 203 by 453, we get 0 and a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 203 and we're left with 203.
Bring next digit (5) of the dividend behind the 203 and repeat the process: 2035 / 453

Moving on to step 4:
If we divide 2035 by 453, we get 4 and a remainder of 223.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1812 from 2035 and we're left with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 453

Moving on to step 5:
2231 divided by 453 is 4 with a remainder of 419.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 419 after subtracting 1812 from 2231.
Grab the next digit (1) from the dividend, add it to 419, then carry on: 4191 / 453

Step 6:
453 goes into 4191 9 times with a remainder of 114.
The next digit of our result is 9. 
Result so far: 449.0
The remainder is 114 after subtracting 4077 from 4191.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 453

Advancing to step 7:
1142 divided by 453 is 2 with a remainder of 236.
The next digit of our result is 2. 
Result so far: 4492.0
If we take 906 away from 1142, we end up with 236.
Include the next digit (3) from the dividend after 236, then repeat: 2363 / 453

Moving on to step 8:
When dividing 2363 by 453, we get 5 with a remainder of 98.
Put 5 as the next digit of the answer. 
Result so far: 44925.0
Deduct 2265 from 2363 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
453 can be fit into 980 2 times, resulting in a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 44925.2
If we subtract 906 from 980, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
740 divided by 453 is 1 with a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 44925.21
If we subtract 453 from 740, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 11:
If we divide 2870 by 453, we get 6 and a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 44925.216
The remainder is 152 after subtracting 2718 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 12:
453 can be fit into 1520 3 times, resulting in a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 44925.2163
Deduct 1359 from 1520 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 13:
453 goes into 1610 3 times with a remainder of 251.
The next digit of our result is 3. 
Result so far: 44925.21633
The remainder is 251 after subtracting 1359 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

The quotient of the division is 44925.21633, and the remainder is 0.000251.
