Let's divide 426154 by 78
We're looking to find how many times 78 goes into 426154.

Moving on to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 78

Step 2:
The number 78 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 78

Moving on to step 3:
78 can be fit into 426 5 times, resulting in a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 390 away from 426, we end up with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 78

Let's proceed to step 4:
If we divide 361 by 78, we get 4 and a remainder of 49.
The next digit of our result is 4. 
Result so far: 54.0
If we take 312 away from 361, we end up with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 78

Moving on to step 5:
495 divided by 78 is 6 with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 546.0
If we subtract 468 from 495, we get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 78

Advancing to step 6:
78 goes into 274 3 times with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 5463.0
If we subtract 234 from 274, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
78 goes into 400 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5463.5
If we subtract 390 from 400, we get 10.
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 8:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 5463.51
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 9:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 5463.512
If we subtract 156 from 220, 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 10:
640 divided by 78 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 5463.5128
Deduct 624 from 640 and we're left 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 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 5463.51282
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5463.51282
Subtracting 0 from 40 leaves us with 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 13:
400 divided by 78 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5463.5128205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 78, we get 1 and a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 5463.51282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 5463.51282051, with a leftover of 2.2e-08.
