We're dividing 78498474 by 48 
We're looking to find how many times 48 goes into 78498474.

Let's proceed to step 1:
7 divided by 48 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 48

Advancing to step 2:
When dividing 78 by 48, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 48 from 78 leaves us with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 48

On to step 3:
When dividing 304 by 48, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 288 from 304 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 48

Going ahead to step 4:
169 divided by 48 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 163.0
Subtracting 144 from 169 leaves us with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 48

Step 5:
When dividing 258 by 48, we get 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 1635.0
The remainder is 18 after subtracting 240 from 258.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 48

Step 6:
When dividing 184 by 48, we get 3 with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 16353.0
Subtracting 144 from 184 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 48

Going ahead to step 7:
407 divided by 48 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 163538.0
Deduct 384 from 407 and we're left with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 48

Let's proceed to step 8:
234 divided by 48 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1635384.0
If we take 192 away from 234, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 48, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 1635384.8
If we take 384 away from 420, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
48 goes into 360 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 1635384.87
If we subtract 336 from 360, we 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 11:
The number 48 fits into 240 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1635384.875
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 48, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1635384.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
The number 48 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1635384.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1635384.875, with a leftover of 0.0.
