Let's divide 834290 by 78
We want to figure out the number of times 834290 can be divided by 78.

On to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 78

Advancing to step 2:
78 goes into 83 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 78 away from 83, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 78

Going ahead to step 3:
The number 78 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 54 leaves us with 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 78

Going ahead to step 4:
542 divided by 78 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtracting 468 from 542 leaves us with 74.
Bring next digit (9) of the dividend behind the 74 and repeat the process: 749 / 78

Going ahead to step 5:
78 can be fit into 749 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 1069.0
If we take 702 away from 749, we end up with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 78

Let's proceed to step 6:
When dividing 470 by 78, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 10696.0
Deduct 468 from 470 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 78, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10696.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
78 goes into 200 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 10696.02
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10696.025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
If we divide 500 by 78, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 10696.0256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
320 divided by 78 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10696.02564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
When dividing 80 by 78, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10696.025641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 78, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10696.025641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 10696.02564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 10696.02564102 and a remainder of 4.4e-08.
