155867 ÷ 78 
We're looking to find how many times 78 goes into 155867.

Going ahead to step 1:
78 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 78

Going ahead to step 2:
When dividing 15 by 78, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 78

On to step 3:
78 goes into 155 1 times with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 155 leaves us with 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 78

Advancing to step 4:
If we divide 778 by 78, we get 9 and a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 702 from 778 and we're left with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 78

Step 5:
The number 78 fits into 766 9 times, leaving a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
The remainder is 64 after subtracting 702 from 766.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 78

Let's proceed to step 6:
When dividing 647 by 78, we get 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 1998.0
Deduct 624 from 647 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
When dividing 230 by 78, we get 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 1998.2
The remainder is 74 after subtracting 156 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1998.29
Subtract 702 from 740 to 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.

On to step 9:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 1998.294
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.

Step 10:
If we divide 680 by 78, we get 8 and a remainder of 56.
The next digit of our result is 8. 
Result so far: 1998.2948
Subtract 624 from 680 to 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.

Advancing to step 11:
78 goes into 560 7 times with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1998.29487
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.

Advancing to step 12:
78 goes into 140 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1998.294871
The remainder is 62 after subtracting 78 from 140.
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:
78 goes into 620 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 1998.2948717
Subtract 546 from 620 to 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.

Let's proceed to step 14:
If we divide 740 by 78, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1998.29487179
If we take 702 away from 740, we end up 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.

Our division results in 1998.29487179 with a remaining 3.8e-08.
