We're dividing 81377366 by 221 
Our goal is to divide 81377366 by 221.

Going ahead to step 1:
8 divided by 221 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 221

On to step 2:
81 divided by 221 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 221

Advancing to step 3:
When dividing 813 by 221, we get 3 with a remainder of 150.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 663 from 813 and we're left with 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 221

Step 4:
If we divide 1507 by 221, we get 6 and a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 1326 from 1507, we get 181.
Append the next digit (7) from the dividend to 181 and continue with: 1817 / 221

Step 5:
If we divide 1817 by 221, we get 8 and a remainder of 49.
The next digit of our result is 8. 
Result so far: 368.0
If we subtract 1768 from 1817, we get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 221

Let's proceed to step 6:
493 divided by 221 is 2 with a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 3682.0
The remainder is 51 after subtracting 442 from 493.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 221

Going ahead to step 7:
221 can be fit into 516 2 times, resulting in a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 36822.0
If we subtract 442 from 516, we get 74.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 221

Let's proceed to step 8:
221 goes into 746 3 times with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 368223.0
If we subtract 663 from 746, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
The number 221 fits into 830 3 times, leaving a remainder of 167.
The next digit of our result is 3. 
Result so far: 368223.3
If we subtract 663 from 830, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 10:
When dividing 1670 by 221, we get 7 with a remainder of 123.
The next digit of our result is 7. 
Result so far: 368223.37
The remainder is 123 after subtracting 1547 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 11:
The number 221 fits into 1230 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 368223.375
The remainder is 125 after subtracting 1105 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
If we divide 1250 by 221, we get 5 and a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 368223.3755
Subtract 1105 from 1250 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The quotient of the division is 368223.3755, and the remainder is 0.00145.
