We're dividing 78184559 by 221 
We're looking to find how many times 221 goes into 78184559.

On to step 1:
If we divide 7 by 221, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 221

Moving on to step 2:
When dividing 78 by 221, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 221

Let's proceed to step 3:
When dividing 781 by 221, we get 3 with a remainder of 118.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 118 after subtracting 663 from 781.
Fetch the next digit (8) from the dividend, attach it to 118 and continue: 1188 / 221

On to step 4:
221 can be fit into 1188 5 times, resulting in a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 1105 from 1188 and we're left with 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 221

Step 5:
If we divide 834 by 221, we get 3 and a remainder of 171.
The next digit of our result is 3. 
Result so far: 353.0
If we take 663 away from 834, we end up with 171.
Include the next digit (5) from the dividend after 171, then repeat: 1715 / 221

Step 6:
221 can be fit into 1715 7 times, resulting in a remainder of 168.
The next digit of our result is 7. 
Result so far: 3537.0
The remainder is 168 after subtracting 1547 from 1715.
Fetch the next digit (5) from the dividend, attach it to 168 and continue: 1685 / 221

Step 7:
When dividing 1685 by 221, we get 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 35377.0
Subtract 1547 from 1685 to get 138.
Fetch the next digit (9) from the dividend, attach it to 138 and continue: 1389 / 221

On to step 8:
If we divide 1389 by 221, we get 6 and a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 353776.0
The remainder is 63 after subtracting 1326 from 1389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
When dividing 630 by 221, we get 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 353776.2
Deduct 442 from 630 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 10:
The number 221 fits into 1880 8 times, leaving a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 353776.28
Subtracting 1768 from 1880 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
221 can be fit into 1120 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 353776.285
Subtract 1105 from 1120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 221, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 353776.285
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
The number 221 fits into 1500 6 times, leaving a remainder of 174.
Put 6 as the next digit of the answer. 
Result so far: 353776.28506
If we subtract 1326 from 1500, we 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 14:
221 can be fit into 1740 7 times, resulting in a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 353776.285067
If we subtract 1547 from 1740, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 15:
The number 221 fits into 1930 8 times, leaving a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 353776.2850678
If we subtract 1768 from 1930, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 16:
221 can be fit into 1620 7 times, resulting in a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 353776.28506787
Subtracting 1547 from 1620 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Our division results in 353776.28506787 with a remaining 7.3e-08.
