987979 ÷ 78 
We're looking to find how many times 78 goes into 987979.

On to step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 78

Let's proceed to step 2:
The number 78 fits into 98 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 98 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 78

Advancing to step 3:
78 can be fit into 207 2 times, resulting in a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 156 from 207 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 78

Going ahead to step 4:
78 can be fit into 519 6 times, resulting in a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 468 away from 519, we end up with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 78

Moving on to step 5:
78 can be fit into 517 6 times, resulting in a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 1266.0
Deduct 468 from 517 and we're left with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 78

Advancing to step 6:
The number 78 fits into 499 6 times, leaving a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 12666.0
Deduct 468 from 499 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 78 is 3 with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 12666.3
If we subtract 234 from 310, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 12666.39
Subtracting 702 from 760 leaves us 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 9:
78 goes into 580 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 12666.397
If we take 546 away from 580, we end up 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.

Let's proceed to step 10:
78 goes into 340 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 12666.3974
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 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 12666.39743
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.

Let's proceed to step 12:
When dividing 460 by 78, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 12666.397435
Deduct 390 from 460 and we're left 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.

Moving on to step 13:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 12666.3974358
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.

Moving on to step 14:
760 divided by 78 is 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 12666.39743589
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.

Our division results in 12666.39743589 with a remaining 5.8e-08.
