550355 ÷ 378 
We're looking to find how many times 378 goes into 550355.

Step 1:
The number 378 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 378

Going ahead to step 2:
If we divide 55 by 378, we get 0 and a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 378

Step 3:
378 can be fit into 550 1 times, resulting in a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 378 from 550 leaves us with 172.
Append the next digit (3) from the dividend to 172 and continue with: 1723 / 378

Advancing to step 4:
When dividing 1723 by 378, we get 4 with a remainder of 211.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 1512 from 1723 and we're left with 211.
Fetch the next digit (5) from the dividend, attach it to 211 and continue: 2115 / 378

Advancing to step 5:
378 can be fit into 2115 5 times, resulting in a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Subtracting 1890 from 2115 leaves us with 225.
Grab the next digit (5) from the dividend, add it to 225, then carry on: 2255 / 378

Moving on to step 6:
If we divide 2255 by 378, we get 5 and a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 1455.0
The remainder is 365 after subtracting 1890 from 2255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 7:
378 goes into 3650 9 times with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 1455.9
Subtracting 3402 from 3650 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 8:
2480 divided by 378 is 6 with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 1455.96
If we subtract 2268 from 2480, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 9:
378 goes into 2120 5 times with a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 1455.965
If we take 1890 away from 2120, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 10:
If we divide 2300 by 378, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1455.9656
Subtracting 2268 from 2300 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 378 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 1455.9656
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
If we divide 3200 by 378, we get 8 and a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 1455.965608
The remainder is 176 after subtracting 3024 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 13:
378 can be fit into 1760 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 1455.9656084
Subtract 1512 from 1760 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
2480 divided by 378 is 6 with a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 1455.96560846
Subtracting 2268 from 2480 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 1455.96560846, and the remainder is 2.12e-07.
