We're dividing 98415949 by 78 
We're looking to find how many times 78 goes into 98415949.

Let's proceed to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 78

Going ahead to step 2:
78 can be fit into 98 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 98 to get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 78

Moving on to step 3:
78 can be fit into 204 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 156 away from 204, we end up with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 78

Advancing to step 4:
481 divided by 78 is 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 468 away from 481, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 78

On to step 5:
The number 78 fits into 135 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1261.0
Subtract 78 from 135 to get 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 78

Step 6:
579 divided by 78 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 12617.0
If we subtract 546 from 579, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 78

Advancing to step 7:
If we divide 334 by 78, we get 4 and a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 126174.0
If we subtract 312 from 334, we get 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 78

Let's proceed to step 8:
229 divided by 78 is 2 with a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 1261742.0
Subtract 156 from 229 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 9:
78 can be fit into 730 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1261742.9
Subtracting 702 from 730 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
280 divided by 78 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1261742.93
If we subtract 234 from 280, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 1261742.935
The remainder is 70 after subtracting 390 from 460.
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 12:
700 divided by 78 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 1261742.9358
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 1261742.93589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
580 divided by 78 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 1261742.935897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
When dividing 340 by 78, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 1261742.9358974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 16:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 1261742.93589743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 1261742.93589743 with a remainder of 4.6e-08.
