We look at the division of 81381406 by 221 
Our goal is to divide 81381406 by 221.

On to step 1:
The number 221 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 221

On to step 2:
221 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 221

Step 3:
If we divide 813 by 221, we get 3 and a remainder of 150.
The next digit of our result is 3. 
Result so far: 3.0
If we take 663 away from 813, we end up with 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 221

Advancing to step 4:
When dividing 1508 by 221, we get 6 with a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Deduct 1326 from 1508 and we're left with 182.
Bring next digit (1) of the dividend behind the 182 and repeat the process: 1821 / 221

Moving on to step 5:
221 can be fit into 1821 8 times, resulting in a remainder of 53.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Deduct 1768 from 1821 and we're left with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 221

Moving on to step 6:
221 can be fit into 534 2 times, resulting in a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 3682.0
If we take 442 away from 534, we end up with 92.
Append the next digit (0) from the dividend to 92 and continue with: 920 / 221

Let's proceed to step 7:
If we divide 920 by 221, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 36824.0
Subtract 884 from 920 to get 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 221

On to step 8:
The number 221 fits into 366 1 times, leaving a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 368241.0
Subtract 221 from 366 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.

On to step 9:
When dividing 1450 by 221, we get 6 with a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 368241.6
If we subtract 1326 from 1450, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 10:
221 goes into 1240 5 times with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 368241.65
Subtracting 1105 from 1240 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
1350 divided by 221 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 368241.656
Subtract 1326 from 1350 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
240 divided by 221 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 368241.6561
Subtracting 221 from 240 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
221 goes into 190 0 times with a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 368241.6561
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 14:
221 goes into 1900 8 times with a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 368241.656108
If we take 1768 away from 1900, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 15:
221 goes into 1320 5 times with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 368241.6561085
Subtract 1105 from 1320 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 16:
221 can be fit into 2150 9 times, resulting in a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 368241.65610859
Subtract 1989 from 2150 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The final result is 368241.65610859 with a remainder of 1.61e-07.
