Let's divide 55434494 by 378
Our goal is to divide 55434494 by 378.

On to step 1:
When dividing 5 by 378, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 378

Advancing to step 2:
When dividing 55 by 378, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 378

Going ahead to step 3:
The number 378 fits into 554 1 times, leaving a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 378 away from 554, we end up with 176.
Take the next digit (3) from the dividend and append it to 176, then repeat: 1763 / 378

Let's proceed to step 4:
When dividing 1763 by 378, we get 4 with a remainder of 251.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1512 from 1763 to get 251.
Append the next digit (4) from the dividend to 251 and continue with: 2514 / 378

Moving on to step 5:
378 can be fit into 2514 6 times, resulting in a remainder of 246.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
If we take 2268 away from 2514, we end up with 246.
Fetch the next digit (4) from the dividend, attach it to 246 and continue: 2464 / 378

On to step 6:
378 goes into 2464 6 times with a remainder of 196.
The next digit of our result is 6. 
Result so far: 1466.0
Deduct 2268 from 2464 and we're left with 196.
Grab the next digit (9) from the dividend, add it to 196, then carry on: 1969 / 378

Moving on to step 7:
1969 divided by 378 is 5 with a remainder of 79.
The number 5 becomes the next digit in our result. 
Result so far: 14665.0
If we subtract 1890 from 1969, we get 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 378

Moving on to step 8:
378 can be fit into 794 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 146652.0
Deduct 756 from 794 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 378 fits into 380 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 146652.1
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 378, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 146652.1
Deduct 0 from 20 and we're left 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 11:
200 divided by 378 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 146652.1
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 146652.1, and the remainder is 0.02.
