209442 ÷ 78 
We're looking to find how many times 78 goes into 209442.

Advancing to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 78

On to step 2:
78 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 78

Going ahead to step 3:
209 divided by 78 is 2 with a remainder of 53.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 156 from 209 to get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 78

Moving on to step 4:
534 divided by 78 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 468 from 534, we get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 78

Going ahead to step 5:
When dividing 664 by 78, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 268.0
If we subtract 624 from 664, we get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 78

Advancing to step 6:
The number 78 fits into 402 5 times, leaving a remainder of 12.
The next digit of our result is 5. 
Result so far: 2685.0
Deduct 390 from 402 and we're left 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.

Advancing to step 7:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 2685.1
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.

Going ahead to step 8:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2685.15
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.

Moving on to step 9:
78 can be fit into 300 3 times, resulting in a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 2685.153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
78 can be fit into 660 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 2685.1538
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.

Advancing to step 11:
The number 78 fits into 360 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 2685.15384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
When dividing 480 by 78, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 2685.153846
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.

Going ahead to step 13:
When dividing 120 by 78, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 2685.1538461
If we take 78 away from 120, we end up 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.

On to step 14:
When dividing 420 by 78, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2685.15384615
If we subtract 390 from 420, we 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.

The final result is 2685.15384615 with a remainder of 3e-08.
