We want to divide 48902199 by 378.

Advancing to step 1:
4 divided by 378 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 378

Going ahead to step 2:
When dividing 48 by 378, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 378

Moving on to step 3:
When dividing 489 by 378, we get 1 with a remainder of 111.
The next digit of our result is 1. 
Result so far: 1.0
If we take 378 away from 489, we end up with 111.
Append the next digit (0) from the dividend to 111 and continue with: 1110 / 378

Advancing to step 4:
1110 divided by 378 is 2 with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 756 from 1110, we get 354.
Include the next digit (2) from the dividend after 354, then repeat: 3542 / 378

Moving on to step 5:
The number 378 fits into 3542 9 times, leaving a remainder of 140.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtracting 3402 from 3542 leaves us with 140.
Append the next digit (1) from the dividend to 140 and continue with: 1401 / 378

Let's proceed to step 6:
1401 divided by 378 is 3 with a remainder of 267.
Put 3 as the next digit of the answer. 
Result so far: 1293.0
Subtract 1134 from 1401 to get 267.
Include the next digit (9) from the dividend after 267, then repeat: 2679 / 378

Let's proceed to step 7:
378 goes into 2679 7 times with a remainder of 33.
The next digit of our result is 7. 
Result so far: 12937.0
If we take 2646 away from 2679, we end up with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 378

On to step 8:
The number 378 fits into 339 0 times, leaving a remainder of 339.
The next digit of our result is 0. 
Result so far: 129370.0
If we take 0 away from 339, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 9:
If we divide 3390 by 378, we get 8 and a remainder of 366.
The next digit of our result is 8. 
Result so far: 129370.8
The remainder is 366 after subtracting 3024 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 10:
When dividing 3660 by 378, we get 9 with a remainder of 258.
The number 9 becomes the next digit in our result. 
Result so far: 129370.89
If we take 3402 away from 3660, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 11:
When dividing 2580 by 378, we get 6 with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 129370.896
Deduct 2268 from 2580 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 12:
When dividing 3120 by 378, we get 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 129370.8968
Subtract 3024 from 3120 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
960 divided by 378 is 2 with a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 129370.89682
Subtracting 756 from 960 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 14:
378 goes into 2040 5 times with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 129370.896825
Subtracting 1890 from 2040 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 15:
378 can be fit into 1500 3 times, resulting in a remainder of 366.
Use 3 as the next digit of our solution. 
Result so far: 129370.8968253
If we subtract 1134 from 1500, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 16:
378 can be fit into 3660 9 times, resulting in a remainder of 258.
The next digit of our result is 9. 
Result so far: 129370.89682539
Subtracting 3402 from 3660 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

In conclusion, the division gives 129370.89682539 with a balance of 2.58e-07.
