We look at the division of 98429837 by 78 
We want to figure out the number of times 98429837 can be divided by 78.

Going ahead to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 78

Going ahead to step 2:
The number 78 fits into 98 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 78 from 98 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 78

Step 3:
204 divided by 78 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 12.0
If we take 156 away from 204, we end up with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 78

Step 4:
482 divided by 78 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 468 away from 482, we end up with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 78

Advancing to step 5:
149 divided by 78 is 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 1261.0
If we subtract 78 from 149, we get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 78

Moving on to step 6:
718 divided by 78 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 12619.0
The remainder is 16 after subtracting 702 from 718.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 78

Going ahead to step 7:
The number 78 fits into 163 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 126192.0
Subtract 156 from 163 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 78

Advancing to step 8:
If we divide 77 by 78, we get 0 and a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 1261920.0
Deduct 0 from 77 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
If we divide 770 by 78, we get 9 and a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 1261920.9
Subtract 702 from 770 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 1261920.98
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1261920.987
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
The number 78 fits into 140 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1261920.9871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
If we divide 620 by 78, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 1261920.98717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
740 divided by 78 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1261920.987179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 15:
When dividing 380 by 78, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 1261920.9871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 16:
If we divide 680 by 78, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 1261920.98717948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 1261920.98717948 with a remaining 5.6e-08.
