We divide 438403 by 55
We want to figure out the number of times 438403 can be divided by 55.

Let's proceed to step 1:
The number 55 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 55

Going ahead to step 2:
55 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 55

On to step 3:
438 divided by 55 is 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 385 from 438 and we're left with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 55

On to step 4:
If we divide 534 by 55, we get 9 and a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtracting 495 from 534 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 55

Moving on to step 5:
390 divided by 55 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 797.0
If we take 385 away from 390, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 55

Moving on to step 6:
If we divide 53 by 55, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 7970.0
The remainder is 53 after subtracting 0 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
55 goes into 530 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 7970.9
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
350 divided by 55 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7970.96
Subtracting 330 from 350 leaves us 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.

Going ahead to step 9:
55 goes into 200 3 times with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 7970.963
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7970.9636
The remainder is 20 after subtracting 330 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 55, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 7970.96363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
If we divide 350 by 55, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7970.963636
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
55 goes into 200 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 7970.9636363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
55 goes into 350 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 7970.96363636
Subtracting 330 from 350 leaves us 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.

The final outcome is 7970.96363636, with a leftover of 2e-08.
