830959 divided by 78 
We want to figure out the number of times 830959 can be divided by 78.

Step 1:
78 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 78

Let's proceed to step 2:
78 goes into 83 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 83 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 78

Advancing to step 3:
78 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 78

Going ahead to step 4:
509 divided by 78 is 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
The remainder is 41 after subtracting 468 from 509.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 78

Step 5:
78 goes into 415 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1065.0
Subtracting 390 from 415 leaves us with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 78

Let's proceed to step 6:
259 divided by 78 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 10653.0
Subtracting 234 from 259 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
If we divide 250 by 78, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 10653.3
Deduct 234 from 250 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 8:
78 goes into 160 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 10653.32
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
78 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10653.32
Deduct 0 from 40 and we're left 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 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: 10653.3205
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.

Advancing to step 11:
The number 78 fits into 100 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10653.32051
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.

Going ahead to step 12:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10653.320512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
When dividing 640 by 78, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 10653.3205128
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.

Step 14:
160 divided by 78 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10653.32051282
Deduct 156 from 160 and we're left with 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 result is 10653.32051282 with a remainder of 4e-09.
