We divide 4903948 by 221
We want to divide 4903948 by 221.

Step 1:
The number 221 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 221

Let's proceed to step 2:
If we divide 49 by 221, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 221

Step 3:
The number 221 fits into 490 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 442 from 490 and we're left with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 221

On to step 4:
221 can be fit into 483 2 times, resulting in a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 442 from 483 to get 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 221

Advancing to step 5:
When dividing 419 by 221, we get 1 with a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we take 221 away from 419, we end up with 198.
Take the next digit (4) from the dividend and append it to 198, then repeat: 1984 / 221

On to step 6:
If we divide 1984 by 221, we get 8 and a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 2218.0
Subtract 1768 from 1984 to get 216.
Grab the next digit (8) from the dividend, add it to 216, then carry on: 2168 / 221

Moving on to step 7:
221 goes into 2168 9 times with a remainder of 179.
Put 9 as the next digit of the answer. 
Result so far: 22189.0
Subtract 1989 from 2168 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.

Going ahead to step 8:
If we divide 1790 by 221, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 22189.8
Deduct 1768 from 1790 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 221, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 22189.8
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
221 can be fit into 2200 9 times, resulting in a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 22189.809
If we subtract 1989 from 2200, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 11:
If we divide 2110 by 221, we get 9 and a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 22189.8099
If we take 1989 away from 2110, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final result is 22189.8099 with a remainder of 0.00121.
