42243820 divided by 454 
We want to figure out the number of times 42243820 can be divided by 454.

On to step 1:
The number 454 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 454

Advancing to step 2:
454 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 454

Going ahead to step 3:
The number 454 fits into 422 0 times, leaving a remainder of 422.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 422, we get 422.
Take the next digit (4) from the dividend and append it to 422, then repeat: 4224 / 454

On to step 4:
If we divide 4224 by 454, we get 9 and a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 4086 from 4224 and we're left with 138.
Fetch the next digit (3) from the dividend, attach it to 138 and continue: 1383 / 454

Advancing to step 5:
454 goes into 1383 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 1362 away from 1383, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 454

Advancing to step 6:
If we divide 218 by 454, we get 0 and a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 930.0
Subtracting 0 from 218 leaves us with 218.
Bring next digit (2) of the dividend behind the 218 and repeat the process: 2182 / 454

Going ahead to step 7:
The number 454 fits into 2182 4 times, leaving a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 9304.0
Subtract 1816 from 2182 to get 366.
Include the next digit (0) from the dividend after 366, then repeat: 3660 / 454

Going ahead to step 8:
When dividing 3660 by 454, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 93048.0
Subtract 3632 from 3660 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 454, we get 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 93048.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
454 can be fit into 2800 6 times, resulting in a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 93048.06
Subtract 2724 from 2800 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
When dividing 760 by 454, we get 1 with a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 93048.061
Subtracting 454 from 760 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 12:
454 can be fit into 3060 6 times, resulting in a remainder of 336.
The number 6 becomes the next digit in our result. 
Result so far: 93048.0616
The remainder is 336 after subtracting 2724 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 13:
454 can be fit into 3360 7 times, resulting in a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 93048.06167
Subtract 3178 from 3360 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 14:
1820 divided by 454 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 93048.061674
If we take 1816 away from 1820, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
The number 454 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 93048.061674
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 16:
400 divided by 454 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 93048.061674
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 93048.061674, with a leftover of 4e-07.
