We look at the division of 45494245 by 451 
We're looking to find how many times 451 goes into 45494245.

Going ahead to step 1:
4 divided by 451 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 451

Step 2:
The number 451 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 451

Advancing to step 3:
451 can be fit into 454 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 451 away from 454, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 451

On to step 4:
When dividing 39 by 451, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 39 to get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 451

Step 5:
The number 451 fits into 394 0 times, leaving a remainder of 394.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 394 after subtracting 0 from 394.
Take the next digit (2) from the dividend and append it to 394, then repeat: 3942 / 451

Advancing to step 6:
451 can be fit into 3942 8 times, resulting in a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 1008.0
Deduct 3608 from 3942 and we're left with 334.
Bring next digit (4) of the dividend behind the 334 and repeat the process: 3344 / 451

Going ahead to step 7:
3344 divided by 451 is 7 with a remainder of 187.
The number 7 becomes the next digit in our result. 
Result so far: 10087.0
Subtracting 3157 from 3344 leaves us with 187.
Take the next digit (5) from the dividend and append it to 187, then repeat: 1875 / 451

Moving on to step 8:
When dividing 1875 by 451, we get 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 100874.0
Deduct 1804 from 1875 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
The number 451 fits into 710 1 times, leaving a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 100874.1
Deduct 451 from 710 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 10:
451 can be fit into 2590 5 times, resulting in a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 100874.15
Subtracting 2255 from 2590 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 11:
If we divide 3350 by 451, we get 7 and a remainder of 193.
The next digit of our result is 7. 
Result so far: 100874.157
If we take 3157 away from 3350, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 12:
451 goes into 1930 4 times with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 100874.1574
If we take 1804 away from 1930, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 13:
1260 divided by 451 is 2 with a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 100874.15742
Deduct 902 from 1260 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 14:
3580 divided by 451 is 7 with a remainder of 423.
Record the quotient 7 as the next digit in the result. 
Result so far: 100874.157427
Subtracting 3157 from 3580 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 15:
451 goes into 4230 9 times with a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 100874.1574279
Subtract 4059 from 4230 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 16:
451 can be fit into 1710 3 times, resulting in a remainder of 357.
The number 3 becomes the next digit in our result. 
Result so far: 100874.15742793
The remainder is 357 after subtracting 1353 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

The final result is 100874.15742793 with a remainder of 3.57e-07.
