We're dividing 83873120 by 221 
Let's see how many times 221 fits into 83873120.

Step 1:
When dividing 8 by 221, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 221

Step 2:
221 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 221

Moving on to step 3:
221 goes into 838 3 times with a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 663 from 838 leaves us with 175.
Append the next digit (7) from the dividend to 175 and continue with: 1757 / 221

Step 4:
If we divide 1757 by 221, we get 7 and a remainder of 210.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 210 after subtracting 1547 from 1757.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 221

On to step 5:
2103 divided by 221 is 9 with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 379.0
Subtracting 1989 from 2103 leaves us with 114.
Include the next digit (1) from the dividend after 114, then repeat: 1141 / 221

Let's proceed to step 6:
When dividing 1141 by 221, we get 5 with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 3795.0
If we subtract 1105 from 1141, we get 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 221

Moving on to step 7:
221 can be fit into 362 1 times, resulting in a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 37951.0
Subtract 221 from 362 to get 141.
Fetch the next digit (0) from the dividend, attach it to 141 and continue: 1410 / 221

On to step 8:
221 goes into 1410 6 times with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 379516.0
Subtract 1326 from 1410 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
221 can be fit into 840 3 times, resulting in a remainder of 177.
Put 3 as the next digit of the answer. 
Result so far: 379516.3
The remainder is 177 after subtracting 663 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 10:
221 can be fit into 1770 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 379516.38
Deduct 1768 from 1770 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
If we divide 20 by 221, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 379516.38
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
221 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 379516.38
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 379516.38 with a remainder of 0.002.
