Let's divide 583426 by 78
We're looking to find how many times 78 goes into 583426.

Step 1:
5 divided by 78 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 78

Step 2:
When dividing 58 by 78, we get 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 78

Advancing to step 3:
78 can be fit into 583 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 7.0
If we take 546 away from 583, we end up with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 78

Moving on to step 4:
78 goes into 374 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 312 from 374 leaves us with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 78

Moving on to step 5:
78 can be fit into 622 7 times, resulting in a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 747.0
Deduct 546 from 622 and we're left with 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 78

Step 6:
If we divide 766 by 78, we get 9 and a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 7479.0
If we subtract 702 from 766, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
If we divide 640 by 78, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7479.8
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 78 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 7479.82
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
78 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7479.82
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.

Advancing to step 10:
If we divide 400 by 78, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7479.8205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 7479.82051
Subtract 78 from 100 to 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.

Let's proceed to step 12:
220 divided by 78 is 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7479.820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
78 goes into 640 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7479.8205128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 78, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7479.82051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 7479.82051282, with a leftover of 4e-09.
