11945574 ÷ 378 
Our goal is to divide 11945574 by 378.

Let's proceed to step 1:
If we divide 1 by 378, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 378

Advancing to step 2:
If we divide 11 by 378, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 378

On to step 3:
119 divided by 378 is 0 with a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 119 leaves us with 119.
Append the next digit (4) from the dividend to 119 and continue with: 1194 / 378

Advancing to step 4:
378 goes into 1194 3 times with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1134 from 1194 to get 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 378

Advancing to step 5:
The number 378 fits into 605 1 times, leaving a remainder of 227.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 378 from 605 and we're left with 227.
Bring next digit (5) of the dividend behind the 227 and repeat the process: 2275 / 378

Going ahead to step 6:
2275 divided by 378 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 316.0
Deduct 2268 from 2275 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 378

Going ahead to step 7:
378 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 3160.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 378

Let's proceed to step 8:
When dividing 774 by 378, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 31602.0
Deduct 756 from 774 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
378 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 31602.0
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
The number 378 fits into 1800 4 times, leaving a remainder of 288.
The next digit of our result is 4. 
Result so far: 31602.04
Deduct 1512 from 1800 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 11:
2880 divided by 378 is 7 with a remainder of 234.
Write down 7 as next digit of the result. 
Result so far: 31602.047
Subtract 2646 from 2880 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 12:
When dividing 2340 by 378, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 31602.0476
Subtract 2268 from 2340 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
When dividing 720 by 378, we get 1 with a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 31602.04761
Subtract 378 from 720 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 14:
3420 divided by 378 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 31602.047619
Subtract 3402 from 3420 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 15:
378 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 31602.047619
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 16:
378 can be fit into 1800 4 times, resulting in a remainder of 288.
Use 4 as the next digit of our solution. 
Result so far: 31602.04761904
If we take 1512 away from 1800, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 31602.04761904, with a leftover of 2.88e-07.
