161502 ÷ 78 
Our goal is to divide 161502 by 78.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 78

On to step 2:
78 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 78

Step 3:
78 goes into 161 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 156 from 161, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 78

Let's proceed to step 4:
55 divided by 78 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 78

On to step 5:
If we divide 550 by 78, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Subtract 546 from 550 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 78

Let's proceed to step 6:
78 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 2070.0
Subtract 0 from 42 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2070.5
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
78 goes into 300 3 times with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 2070.53
Deduct 234 from 300 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
78 goes into 660 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 2070.538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 2070.5384
If we subtract 312 from 360, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
If we divide 480 by 78, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 2070.53846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
78 can be fit into 120 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 2070.538461
Deduct 78 from 120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
If we divide 420 by 78, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2070.5384615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 2070.53846153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 2070.53846153 with a remaining 6.6e-08.
