89980 divided by 78 
Let's see how many times 78 fits into 89980.

Advancing to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 78

On to step 2:
89 divided by 78 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 78 from 89 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 78

Moving on to step 3:
The number 78 fits into 119 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 78 from 119, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 78

On to step 4:
If we divide 418 by 78, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 115.0
The remainder is 28 after subtracting 390 from 418.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 78

Let's proceed to step 5:
280 divided by 78 is 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1153.0
Deduct 234 from 280 and we're left with 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 6:
When dividing 460 by 78, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1153.5
If we take 390 away from 460, we end up 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.

Going ahead to step 7:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 1153.58
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.

Advancing to step 8:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 1153.589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
When dividing 580 by 78, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 1153.5897
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 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 1153.58974
If we take 312 away from 340, we end up 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.

Let's proceed to step 11:
78 goes into 280 3 times with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 1153.589743
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.

Advancing to step 12:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1153.5897435
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.

Advancing to step 13:
When dividing 700 by 78, we get 8 with a remainder of 76.
The next digit of our result is 8. 
Result so far: 1153.58974358
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.

Our division results in 1153.58974358 with a remaining 7.6e-08.
