We're dividing 986521 by 78 
We're looking to find how many times 78 goes into 986521.

Moving on to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 78

Advancing to step 2:
78 goes into 98 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we take 78 away from 98, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 78

Advancing to step 3:
The number 78 fits into 206 2 times, leaving a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 156 away from 206, we end up with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 78

Step 4:
When dividing 505 by 78, we get 6 with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 126.0
The remainder is 37 after subtracting 468 from 505.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 78

Going ahead to step 5:
78 goes into 372 4 times with a remainder of 60.
The next digit of our result is 4. 
Result so far: 1264.0
If we take 312 away from 372, we end up with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 78

On to step 6:
78 can be fit into 601 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 12647.0
If we subtract 546 from 601, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
If we divide 550 by 78, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 12647.7
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 78, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12647.7
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 12647.705
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 78 fits into 100 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 12647.7051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 12647.70512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
78 can be fit into 640 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12647.705128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12647.7051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 78, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12647.7051282
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 12647.7051282 and a remainder of 4e-08.
