We divide 6830586 by 78
Our goal is to divide 6830586 by 78.

On to step 1:
78 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 78

Let's proceed to step 2:
78 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 78

Advancing to step 3:
78 can be fit into 683 8 times, resulting in a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 624 from 683 leaves us with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 78

Going ahead to step 4:
78 can be fit into 590 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 546 from 590 and we're left with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 78

Step 5:
78 can be fit into 445 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 875.0
Deduct 390 from 445 and we're left with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 78

On to step 6:
If we divide 558 by 78, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 8757.0
If we subtract 546 from 558, we get 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 78

On to step 7:
126 divided by 78 is 1 with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 87571.0
The remainder is 48 after subtracting 78 from 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 87571.6
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 78 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 87571.61
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 87571.615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
When dividing 300 by 78, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 87571.6153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 87571.61538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
When dividing 360 by 78, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 87571.615384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
78 goes into 480 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 87571.6153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
If we divide 120 by 78, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 87571.61538461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 87571.61538461 with a remainder of 4.2e-08.
