126622 divided by 78 
Let's see how many times 78 fits into 126622.

Step 1:
78 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 78

Going ahead to step 2:
78 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 78

On to step 3:
The number 78 fits into 126 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 78 from 126 leaves us with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 78

Step 4:
78 goes into 486 6 times with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 468 from 486 to get 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 78

Advancing to step 5:
78 can be fit into 182 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 162.0
The remainder is 26 after subtracting 156 from 182.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 78

Let's proceed to step 6:
When dividing 262 by 78, we get 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1623.0
Subtracting 234 from 262 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
78 can be fit into 280 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1623.3
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 1623.35
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The next digit of our result is 8. 
Result so far: 1623.358
If we take 624 away from 700, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 1623.3589
If we subtract 702 from 760, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
580 divided by 78 is 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 1623.35897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1623.358974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
78 goes into 280 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 1623.3589743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
If we divide 460 by 78, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 1623.35897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1623.35897435 with a remaining 7e-08.
