Let's divide 19413653 by 221
We want to figure out the number of times 19413653 can be divided by 221.

Going ahead to step 1:
If we divide 1 by 221, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 221

Going ahead to step 2:
221 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 221

Moving on to step 3:
194 divided by 221 is 0 with a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 194 to get 194.
Include the next digit (1) from the dividend after 194, then repeat: 1941 / 221

Going ahead to step 4:
When dividing 1941 by 221, we get 8 with a remainder of 173.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 1768 from 1941, we get 173.
Fetch the next digit (3) from the dividend, attach it to 173 and continue: 1733 / 221

Going ahead to step 5:
1733 divided by 221 is 7 with a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 1547 from 1733 and we're left with 186.
Fetch the next digit (6) from the dividend, attach it to 186 and continue: 1866 / 221

On to step 6:
If we divide 1866 by 221, we get 8 and a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
The remainder is 98 after subtracting 1768 from 1866.
Take the next digit (5) from the dividend and append it to 98, then repeat: 985 / 221

Let's proceed to step 7:
If we divide 985 by 221, we get 4 and a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 8784.0
If we subtract 884 from 985, we get 101.
Include the next digit (3) from the dividend after 101, then repeat: 1013 / 221

Advancing to step 8:
1013 divided by 221 is 4 with a remainder of 129.
The number 4 becomes the next digit in our result. 
Result so far: 87844.0
Deduct 884 from 1013 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
If we divide 1290 by 221, we get 5 and a remainder of 185.
The next digit of our result is 5. 
Result so far: 87844.5
The remainder is 185 after subtracting 1105 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 10:
If we divide 1850 by 221, we get 8 and a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 87844.58
Subtract 1768 from 1850 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
820 divided by 221 is 3 with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 87844.583
If we take 663 away from 820, we end up 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.

Going ahead to step 12:
221 can be fit into 1570 7 times, resulting in a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 87844.5837
If we subtract 1547 from 1570, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
The number 221 fits into 230 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 87844.58371
Deduct 221 from 230 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
90 divided by 221 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 87844.58371
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 15:
The number 221 fits into 900 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 87844.5837104
Deduct 884 from 900 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
160 divided by 221 is 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 87844.5837104
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 87844.5837104 with a remainder of 1.6e-07.
