We're dividing 66220503 by 440 
We want to divide 66220503 by 440.

Step 1:
The number 440 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 440

Going ahead to step 2:
If we divide 66 by 440, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 440

On to step 3:
If we divide 662 by 440, we get 1 and a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 440 from 662 leaves us with 222.
Append the next digit (2) from the dividend to 222 and continue with: 2222 / 440

Step 4:
The number 440 fits into 2222 5 times, leaving a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 2200 from 2222 to get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 440

Advancing to step 5:
440 can be fit into 220 0 times, resulting in a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 220, we end up with 220.
Append the next digit (5) from the dividend to 220 and continue with: 2205 / 440

Moving on to step 6:
2205 divided by 440 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1505.0
Subtracting 2200 from 2205 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 440

Moving on to step 7:
440 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 15050.0
If we take 0 away from 50, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 440

Going ahead to step 8:
440 goes into 503 1 times with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 150501.0
If we subtract 440 from 503, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
The number 440 fits into 630 1 times, leaving a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 150501.1
Subtracting 440 from 630 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
If we divide 1900 by 440, we get 4 and a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 150501.14
Subtracting 1760 from 1900 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
The number 440 fits into 1400 3 times, leaving a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 150501.143
The remainder is 80 after subtracting 1320 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
The number 440 fits into 800 1 times, leaving a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 150501.1431
If we subtract 440 from 800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
440 can be fit into 3600 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 150501.14318
If we take 3520 away from 3600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
The number 440 fits into 800 1 times, leaving a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 150501.143181
Deduct 440 from 800 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 15:
3600 divided by 440 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 150501.1431818
If we subtract 3520 from 3600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
The number 440 fits into 800 1 times, leaving a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 150501.14318181
If we subtract 440 from 800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 150501.14318181 with a remainder of 3.6e-07.
