73707109 ÷ 378 
We want to figure out the number of times 73707109 can be divided by 378.

Moving on to step 1:
7 divided by 378 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 378

On to step 2:
The number 378 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 378

Going ahead to step 3:
When dividing 737 by 378, we get 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 378 from 737 and we're left with 359.
Bring next digit (0) of the dividend behind the 359 and repeat the process: 3590 / 378

Let's proceed to step 4:
378 can be fit into 3590 9 times, resulting in a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 3402 from 3590 to get 188.
Take the next digit (7) from the dividend and append it to 188, then repeat: 1887 / 378

Let's proceed to step 5:
1887 divided by 378 is 4 with a remainder of 375.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Subtracting 1512 from 1887 leaves us with 375.
Take the next digit (1) from the dividend and append it to 375, then repeat: 3751 / 378

Step 6:
3751 divided by 378 is 9 with a remainder of 349.
Put 9 as the next digit of the answer. 
Result so far: 1949.0
If we subtract 3402 from 3751, we get 349.
Take the next digit (0) from the dividend and append it to 349, then repeat: 3490 / 378

On to step 7:
When dividing 3490 by 378, we get 9 with a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 19499.0
If we subtract 3402 from 3490, we get 88.
Grab the next digit (9) from the dividend, add it to 88, then carry on: 889 / 378

Advancing to step 8:
889 divided by 378 is 2 with a remainder of 133.
Record the quotient 2 as the next digit in the result. 
Result so far: 194992.0
If we subtract 756 from 889, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
378 goes into 1330 3 times with a remainder of 196.
The next digit of our result is 3. 
Result so far: 194992.3
If we subtract 1134 from 1330, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 10:
If we divide 1960 by 378, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 194992.35
Subtract 1890 from 1960 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
378 can be fit into 700 1 times, resulting in a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 194992.351
Subtract 378 from 700 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 12:
3220 divided by 378 is 8 with a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 194992.3518
Deduct 3024 from 3220 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 13:
1960 divided by 378 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 194992.35185
Subtract 1890 from 1960 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
378 can be fit into 700 1 times, resulting in a remainder of 322.
Put 1 as the next digit of the answer. 
Result so far: 194992.351851
If we take 378 away from 700, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 15:
378 goes into 3220 8 times with a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 194992.3518518
If we subtract 3024 from 3220, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 16:
The number 378 fits into 1960 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 194992.35185185
Subtract 1890 from 1960 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 194992.35185185 with a remaining 7e-08.
