Let's divide 78938349 by 215
We're looking to find how many times 215 goes into 78938349.

Step 1:
7 divided by 215 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 215

Let's proceed to step 2:
215 can be fit into 78 0 times, resulting in a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 215

Step 3:
When dividing 789 by 215, we get 3 with a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 645 away from 789, we end up with 144.
Grab the next digit (3) from the dividend, add it to 144, then carry on: 1443 / 215

Advancing to step 4:
The number 215 fits into 1443 6 times, leaving a remainder of 153.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 1290 away from 1443, we end up with 153.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 215

Moving on to step 5:
When dividing 1538 by 215, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
If we take 1505 away from 1538, we end up with 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 215

Advancing to step 6:
215 goes into 333 1 times with a remainder of 118.
The next digit of our result is 1. 
Result so far: 3671.0
Deduct 215 from 333 and we're left with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 215

On to step 7:
1184 divided by 215 is 5 with a remainder of 109.
Write down 5 as next digit of the result. 
Result so far: 36715.0
If we take 1075 away from 1184, we end up with 109.
Bring next digit (9) of the dividend behind the 109 and repeat the process: 1099 / 215

Step 8:
215 can be fit into 1099 5 times, resulting in a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 367155.0
Subtract 1075 from 1099 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
The number 215 fits into 240 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 367155.1
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
If we divide 250 by 215, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 367155.11
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 367155.11 with a remainder of 0.035.
