45882878 ÷ 378 
Our goal is to divide 45882878 by 378.

Advancing to step 1:
When dividing 4 by 378, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 378

Moving on to step 2:
If we divide 45 by 378, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 378

Let's proceed to step 3:
The number 378 fits into 458 1 times, leaving a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 378 away from 458, we end up with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 378

Moving on to step 4:
When dividing 808 by 378, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 756 from 808 leaves us with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 378

Step 5:
When dividing 522 by 378, we get 1 with a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 378 from 522 to get 144.
Fetch the next digit (8) from the dividend, attach it to 144 and continue: 1448 / 378

On to step 6:
When dividing 1448 by 378, we get 3 with a remainder of 314.
Write down 3 as next digit of the result. 
Result so far: 1213.0
The remainder is 314 after subtracting 1134 from 1448.
Append the next digit (7) from the dividend to 314 and continue with: 3147 / 378

On to step 7:
378 goes into 3147 8 times with a remainder of 123.
The next digit of our result is 8. 
Result so far: 12138.0
The remainder is 123 after subtracting 3024 from 3147.
Include the next digit (8) from the dividend after 123, then repeat: 1238 / 378

Moving on to step 8:
The number 378 fits into 1238 3 times, leaving a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 121383.0
The remainder is 104 after subtracting 1134 from 1238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
1040 divided by 378 is 2 with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 121383.2
The remainder is 284 after subtracting 756 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 10:
378 goes into 2840 7 times with a remainder of 194.
Use 7 as the next digit of our solution. 
Result so far: 121383.27
If we subtract 2646 from 2840, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 11:
If we divide 1940 by 378, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 121383.275
Deduct 1890 from 1940 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
378 can be fit into 500 1 times, resulting in a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 121383.2751
Deduct 378 from 500 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 13:
If we divide 1220 by 378, we get 3 and a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 121383.27513
Subtracting 1134 from 1220 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 14:
378 goes into 860 2 times with a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 121383.275132
Deduct 756 from 860 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
378 can be fit into 1040 2 times, resulting in a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 121383.2751322
Subtracting 756 from 1040 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final result is 121383.2751322 with a remainder of 2.84e-06.
