We look at the division of 55390646 by 178 
We're looking to find how many times 178 goes into 55390646.

Step 1:
When dividing 5 by 178, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 178

Moving on to step 2:
55 divided by 178 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 178

Step 3:
553 divided by 178 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 534 from 553 to get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 178

Moving on to step 4:
178 goes into 199 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 178 from 199 leaves us with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 178

Moving on to step 5:
178 can be fit into 210 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 311.0
Subtracting 178 from 210 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 178

Step 6:
If we divide 326 by 178, we get 1 and a remainder of 148.
Record the quotient 1 as the next digit in the result. 
Result so far: 3111.0
If we take 178 away from 326, we end up with 148.
Take the next digit (4) from the dividend and append it to 148, then repeat: 1484 / 178

Advancing to step 7:
If we divide 1484 by 178, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 31118.0
Subtracting 1424 from 1484 leaves us with 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 178

Moving on to step 8:
The number 178 fits into 606 3 times, leaving a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 311183.0
Subtract 534 from 606 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
178 can be fit into 720 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 311183.4
Subtract 712 from 720 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 178, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 311183.4
Deduct 0 from 80 and we're left 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.

Going ahead to step 11:
178 goes into 800 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 311183.404
If we subtract 712 from 800, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
178 can be fit into 880 4 times, resulting in a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 311183.4044
If we take 712 away from 880, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 311183.4044 with a remainder of 0.00168.
