We divide 45978790 by 378
We want to figure out the number of times 45978790 can be divided by 378.

Let's proceed 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
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 378

Going ahead to step 2:
378 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 378

Advancing to step 3:
If we divide 459 by 378, we get 1 and a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 378 from 459 and we're left with 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 378

Going ahead to step 4:
817 divided by 378 is 2 with a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 756 from 817 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 378

Going ahead to step 5:
378 can be fit into 618 1 times, resulting in a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 378 away from 618, we end up with 240.
Grab the next digit (7) from the dividend, add it to 240, then carry on: 2407 / 378

Let's proceed to step 6:
2407 divided by 378 is 6 with a remainder of 139.
Record the quotient 6 as the next digit in the result. 
Result so far: 1216.0
If we subtract 2268 from 2407, we get 139.
Fetch the next digit (9) from the dividend, attach it to 139 and continue: 1399 / 378

Advancing to step 7:
If we divide 1399 by 378, we get 3 and a remainder of 265.
Write down 3 as next digit of the result. 
Result so far: 12163.0
Subtract 1134 from 1399 to get 265.
Grab the next digit (0) from the dividend, add it to 265, then carry on: 2650 / 378

On to step 8:
2650 divided by 378 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 121637.0
If we take 2646 away from 2650, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 378, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 121637.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 378 fits into 400 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 121637.01
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 378, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 121637.01
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
2200 divided by 378 is 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 121637.0105
Subtracting 1890 from 2200 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 13:
378 goes into 3100 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 121637.01058
If we subtract 3024 from 3100, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
378 can be fit into 760 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 121637.010582
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
378 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 121637.010582
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
378 can be fit into 400 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 121637.01058201
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 121637.01058201, with a leftover of 2.2e-08.
