45911212 ÷ 453 
We want to figure out the number of times 45911212 can be divided by 453.

Going ahead to step 1:
When dividing 4 by 453, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 453

Moving on to step 2:
When dividing 45 by 453, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 453

Let's proceed to step 3:
453 goes into 459 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 453 from 459 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 453

Step 4:
453 goes into 61 0 times with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 61, we end up with 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 453

Advancing to step 5:
611 divided by 453 is 1 with a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Deduct 453 from 611 and we're left with 158.
Include the next digit (2) from the dividend after 158, then repeat: 1582 / 453

Step 6:
1582 divided by 453 is 3 with a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 1013.0
The remainder is 223 after subtracting 1359 from 1582.
Take the next digit (1) from the dividend and append it to 223, then repeat: 2231 / 453

Step 7:
If we divide 2231 by 453, we get 4 and a remainder of 419.
Put 4 as the next digit of the answer. 
Result so far: 10134.0
Subtract 1812 from 2231 to get 419.
Append the next digit (2) from the dividend to 419 and continue with: 4192 / 453

On to step 8:
453 can be fit into 4192 9 times, resulting in a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 101349.0
Subtract 4077 from 4192 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 9:
453 goes into 1150 2 times with a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 101349.2
Deduct 906 from 1150 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 10:
453 can be fit into 2440 5 times, resulting in a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 101349.25
Deduct 2265 from 2440 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
If we divide 1750 by 453, we get 3 and a remainder of 391.
The next digit of our result is 3. 
Result so far: 101349.253
If we take 1359 away from 1750, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Going ahead to step 12:
When dividing 3910 by 453, we get 8 with a remainder of 286.
Record the quotient 8 as the next digit in the result. 
Result so far: 101349.2538
The remainder is 286 after subtracting 3624 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 13:
453 goes into 2860 6 times with a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 101349.25386
Deduct 2718 from 2860 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 14:
453 can be fit into 1420 3 times, resulting in a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 101349.253863
If we subtract 1359 from 1420, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 15:
When dividing 610 by 453, we get 1 with a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 101349.2538631
Deduct 453 from 610 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 16:
1570 divided by 453 is 3 with a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 101349.25386313
Subtract 1359 from 1570 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The final outcome is 101349.25386313, with a leftover of 2.11e-07.
