42240154 ÷ 221 
We want to figure out the number of times 42240154 can be divided by 221.

Let's proceed to step 1:
The number 221 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 221

On to step 2:
42 divided by 221 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 221

Advancing to step 3:
When dividing 422 by 221, we get 1 with a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 201 after subtracting 221 from 422.
Grab the next digit (4) from the dividend, add it to 201, then carry on: 2014 / 221

Going ahead to step 4:
When dividing 2014 by 221, we get 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 25 after subtracting 1989 from 2014.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 221

Step 5:
221 goes into 250 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtracting 221 from 250 leaves us with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 221

Moving on to step 6:
If we divide 291 by 221, we get 1 and a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1911.0
Deduct 221 from 291 and we're left with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 221

Moving on to step 7:
221 goes into 705 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 19113.0
Deduct 663 from 705 and we're left with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 221

Going ahead to step 8:
221 can be fit into 424 1 times, resulting in a remainder of 203.
Use 1 as the next digit of our solution. 
Result so far: 191131.0
If we subtract 221 from 424, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
When dividing 2030 by 221, we get 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 191131.9
If we take 1989 away from 2030, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
When dividing 410 by 221, we get 1 with a remainder of 189.
The next digit of our result is 1. 
Result so far: 191131.91
Subtracting 221 from 410 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 11:
When dividing 1890 by 221, we get 8 with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 191131.918
If we take 1768 away from 1890, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 12:
When dividing 1220 by 221, we get 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 191131.9185
Subtracting 1105 from 1220 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
221 goes into 1150 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 191131.91855
If we take 1105 away from 1150, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 191131.91855, and the remainder is 4.5e-05.
