We look at the division of 38748634 by 221 
We want to figure out the number of times 38748634 can be divided by 221.

Advancing to step 1:
The number 221 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 221

Moving on to step 2:
221 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 221

Step 3:
221 goes into 387 1 times with a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 221 from 387 leaves us with 166.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 221

On to step 4:
1664 divided by 221 is 7 with a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 1547 away from 1664, we end up with 117.
Bring next digit (8) of the dividend behind the 117 and repeat the process: 1178 / 221

Advancing to step 5:
When dividing 1178 by 221, we get 5 with a remainder of 73.
The next digit of our result is 5. 
Result so far: 175.0
The remainder is 73 after subtracting 1105 from 1178.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 221

Moving on to step 6:
The number 221 fits into 736 3 times, leaving a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 1753.0
If we take 663 away from 736, we end up with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 221

Step 7:
221 can be fit into 733 3 times, resulting in a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 17533.0
The remainder is 70 after subtracting 663 from 733.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 221

Step 8:
If we divide 704 by 221, we get 3 and a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 175333.0
The remainder is 41 after subtracting 663 from 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
410 divided by 221 is 1 with a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 175333.1
If we take 221 away from 410, we end up 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 10:
221 can be fit into 1890 8 times, resulting in a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 175333.18
Subtract 1768 from 1890 to get 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 11:
If we divide 1220 by 221, we get 5 and a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 175333.185
Deduct 1105 from 1220 and we're left 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.

Advancing to step 12:
When dividing 1150 by 221, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 175333.1855
Subtract 1105 from 1150 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

In conclusion, the division gives 175333.1855 with a balance of 0.00045.
