We're dividing 55603113 by 173 
We want to divide 55603113 by 173.

Going ahead to step 1:
When dividing 5 by 173, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 173

Step 2:
55 divided by 173 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 173

Moving on to step 3:
The number 173 fits into 556 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 519 from 556 to get 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 173

Step 4:
When dividing 370 by 173, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtract 346 from 370 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 173

On to step 5:
When dividing 243 by 173, we get 1 with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
The remainder is 70 after subtracting 173 from 243.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 173

Moving on to step 6:
701 divided by 173 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 3214.0
Subtracting 692 from 701 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 173

Let's proceed to step 7:
If we divide 91 by 173, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 32140.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 173

Moving on to step 8:
The number 173 fits into 913 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 321405.0
If we take 865 away from 913, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 173, we get 2 with a remainder of 134.
The number 2 becomes the next digit in our result. 
Result so far: 321405.2
Subtract 346 from 480 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
173 goes into 1340 7 times with a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 321405.27
If we subtract 1211 from 1340, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 11:
When dividing 1290 by 173, we get 7 with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 321405.277
Subtracting 1211 from 1290 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 321405.277 with a remaining 0.0079.
