Let's divide 899408 by 78
We're looking to find how many times 78 goes into 899408.

Going ahead to step 1:
78 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 78

Going ahead to step 2:
If we divide 89 by 78, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 89 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 78

Advancing to step 3:
When dividing 119 by 78, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 78 from 119, we get 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 78

On to step 4:
When dividing 414 by 78, we get 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Deduct 390 from 414 and we're left with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 78

Advancing to step 5:
If we divide 240 by 78, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 1153.0
The remainder is 6 after subtracting 234 from 240.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 78

Moving on to step 6:
When dividing 68 by 78, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 11530.0
Subtracting 0 from 68 leaves us 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 7:
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: 11530.8
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.

Moving on to step 8:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 11530.87
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
140 divided by 78 is 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 11530.871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 11530.8717
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
78 goes into 740 9 times with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 11530.87179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 78 fits into 380 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 11530.871794
Subtracting 312 from 380 leaves us 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.

On to step 13:
680 divided by 78 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 11530.8717948
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.

Advancing to step 14:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 11530.87179487
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.

The final outcome is 11530.87179487, with a leftover of 1.4e-08.
