Let's divide 37215678 by 878
Let's see how many times 878 fits into 37215678.

Advancing to step 1:
878 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 878

Advancing to step 2:
If we divide 37 by 878, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 878

Step 3:
878 goes into 372 0 times with a remainder of 372.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 372, we get 372.
Grab the next digit (1) from the dividend, add it to 372, then carry on: 3721 / 878

Advancing to step 4:
878 can be fit into 3721 4 times, resulting in a remainder of 209.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3512 from 3721, we get 209.
Take the next digit (5) from the dividend and append it to 209, then repeat: 2095 / 878

Advancing to step 5:
If we divide 2095 by 878, we get 2 and a remainder of 339.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1756 from 2095, we get 339.
Bring next digit (6) of the dividend behind the 339 and repeat the process: 3396 / 878

Advancing to step 6:
When dividing 3396 by 878, we get 3 with a remainder of 762.
The next digit of our result is 3. 
Result so far: 423.0
Subtracting 2634 from 3396 leaves us with 762.
Grab the next digit (7) from the dividend, add it to 762, then carry on: 7627 / 878

Advancing to step 7:
878 can be fit into 7627 8 times, resulting in a remainder of 603.
Record the quotient 8 as the next digit in the result. 
Result so far: 4238.0
If we take 7024 away from 7627, we end up with 603.
Include the next digit (8) from the dividend after 603, then repeat: 6038 / 878

Moving on to step 8:
The number 878 fits into 6038 6 times, leaving a remainder of 770.
Record the quotient 6 as the next digit in the result. 
Result so far: 42386.0
Subtract 5268 from 6038 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

On to step 9:
878 goes into 7700 8 times with a remainder of 676.
The next digit of our result is 8. 
Result so far: 42386.8
If we subtract 7024 from 7700, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Let's proceed to step 10:
6760 divided by 878 is 7 with a remainder of 614.
Record the quotient 7 as the next digit in the result. 
Result so far: 42386.87
If we take 6146 away from 6760, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 11:
The number 878 fits into 6140 6 times, leaving a remainder of 872.
Put 6 as the next digit of the answer. 
Result so far: 42386.876
Subtract 5268 from 6140 to get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Let's proceed to step 12:
878 goes into 8720 9 times with a remainder of 818.
The next digit of our result is 9. 
Result so far: 42386.8769
The remainder is 818 after subtracting 7902 from 8720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Step 13:
8180 divided by 878 is 9 with a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 42386.87699
Subtracting 7902 from 8180 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final outcome is 42386.87699, with a leftover of 0.000278.
