We look at the division of 49985803 by 378 
Let's see how many times 378 fits into 49985803.

Going ahead to step 1:
378 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 378

On to step 2:
When dividing 49 by 378, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 378

Advancing to step 3:
499 divided by 378 is 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 378 from 499 and we're left with 121.
Fetch the next digit (8) from the dividend, attach it to 121 and continue: 1218 / 378

Advancing to step 4:
1218 divided by 378 is 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1134 from 1218, we get 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 378

Advancing to step 5:
378 can be fit into 845 2 times, resulting in a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we subtract 756 from 845, we get 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 378

On to step 6:
The number 378 fits into 898 2 times, leaving a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 1322.0
If we subtract 756 from 898, we get 142.
Take the next digit (0) from the dividend and append it to 142, then repeat: 1420 / 378

Advancing to step 7:
The number 378 fits into 1420 3 times, leaving a remainder of 286.
Record the quotient 3 as the next digit in the result. 
Result so far: 13223.0
Subtracting 1134 from 1420 leaves us with 286.
Bring next digit (3) of the dividend behind the 286 and repeat the process: 2863 / 378

Let's proceed to step 8:
If we divide 2863 by 378, we get 7 and a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 132237.0
Subtract 2646 from 2863 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Step 9:
2170 divided by 378 is 5 with a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 132237.5
Deduct 1890 from 2170 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
The number 378 fits into 2800 7 times, leaving a remainder of 154.
The number 7 becomes the next digit in our result. 
Result so far: 132237.57
The remainder is 154 after subtracting 2646 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 11:
378 can be fit into 1540 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 132237.574
If we take 1512 away from 1540, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
378 goes into 280 0 times with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 132237.574
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
378 can be fit into 2800 7 times, resulting in a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 132237.57407
Subtract 2646 from 2800 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 14:
When dividing 1540 by 378, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 132237.574074
If we take 1512 away from 1540, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
378 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 132237.574074
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
378 can be fit into 2800 7 times, resulting in a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 132237.57407407
Subtract 2646 from 2800 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 132237.57407407, with a leftover of 1.54e-07.
