42551919 divided by 223 
We want to figure out the number of times 42551919 can be divided by 223.

Going ahead to step 1:
223 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 223

Let's proceed to step 2:
223 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 223

Moving on to step 3:
425 divided by 223 is 1 with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 202 after subtracting 223 from 425.
Append the next digit (5) from the dividend to 202 and continue with: 2025 / 223

Going ahead to step 4:
223 goes into 2025 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 2007 away from 2025, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 223

Moving on to step 5:
223 goes into 181 0 times with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we take 0 away from 181, we end up with 181.
Take the next digit (9) from the dividend and append it to 181, then repeat: 1819 / 223

On to step 6:
If we divide 1819 by 223, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 1908.0
Deduct 1784 from 1819 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 223

Advancing to step 7:
223 can be fit into 351 1 times, resulting in a remainder of 128.
Use 1 as the next digit of our solution. 
Result so far: 19081.0
The remainder is 128 after subtracting 223 from 351.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 223

Advancing to step 8:
1289 divided by 223 is 5 with a remainder of 174.
The number 5 becomes the next digit in our result. 
Result so far: 190815.0
Subtract 1115 from 1289 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
1740 divided by 223 is 7 with a remainder of 179.
The next digit of our result is 7. 
Result so far: 190815.7
Subtract 1561 from 1740 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 10:
223 goes into 1790 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 190815.78
Deduct 1784 from 1790 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
The number 223 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 190815.78
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
The number 223 fits into 600 2 times, leaving a remainder of 154.
The next digit of our result is 2. 
Result so far: 190815.7802
Subtract 446 from 600 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 13:
223 can be fit into 1540 6 times, resulting in a remainder of 202.
Record the quotient 6 as the next digit in the result. 
Result so far: 190815.78026
Deduct 1338 from 1540 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 14:
The number 223 fits into 2020 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 190815.780269
Subtracting 2007 from 2020 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 15:
When dividing 130 by 223, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 190815.780269
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
When dividing 1300 by 223, we get 5 with a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 190815.78026905
Subtracting 1115 from 1300 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final result is 190815.78026905 with a remainder of 1.85e-07.
