Let's divide 98902435 by 78
We're looking to find how many times 78 goes into 98902435.

Step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 78

Moving on to step 2:
78 can be fit into 98 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 78 from 98, we get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 78

Advancing to step 3:
78 goes into 209 2 times with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 156 from 209 and we're left with 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 78

Let's proceed to step 4:
78 goes into 530 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Subtract 468 from 530 to get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 78

Advancing to step 5:
78 goes into 622 7 times with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
If we take 546 away from 622, we end up with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 78

Going ahead to step 6:
78 goes into 764 9 times with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 12679.0
If we subtract 702 from 764, we get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 78

On to step 7:
If we divide 623 by 78, we get 7 and a remainder of 77.
The next digit of our result is 7. 
Result so far: 126797.0
Deduct 546 from 623 and we're left with 77.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 78

Step 8:
If we divide 775 by 78, we get 9 and a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 1267979.0
The remainder is 73 after subtracting 702 from 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
When dividing 730 by 78, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1267979.9
Subtract 702 from 730 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1267979.93
The remainder is 46 after subtracting 234 from 280.
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:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1267979.935
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 1267979.9358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 1267979.93589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 1267979.935897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 15:
If we divide 340 by 78, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1267979.9358974
Subtracting 312 from 340 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 16:
When dividing 280 by 78, we get 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 1267979.93589743
The remainder is 46 after subtracting 234 from 280.
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 outcome is 1267979.93589743, with a leftover of 4.6e-08.
