We divide 5164091 by 78
Our goal is to divide 5164091 by 78.

Advancing to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 78

Advancing to step 2:
When dividing 51 by 78, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 78

Let's proceed to step 3:
516 divided by 78 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 48 after subtracting 468 from 516.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 78

On to step 4:
78 goes into 484 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 468 from 484 leaves us with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 78

On to step 5:
160 divided by 78 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 662.0
Subtracting 156 from 160 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 78

Advancing to step 6:
The number 78 fits into 49 0 times, leaving a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 6620.0
Deduct 0 from 49 and we're left with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 78

Going ahead to step 7:
When dividing 491 by 78, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 66206.0
Subtract 468 from 491 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
78 can be fit into 230 2 times, resulting in a remainder of 74.
Write down 2 as next digit of the result. 
Result so far: 66206.2
If we subtract 156 from 230, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
If we divide 740 by 78, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 66206.29
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
When dividing 380 by 78, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 66206.294
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 66206.2948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
If we divide 560 by 78, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 66206.29487
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 66206.294871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
78 goes into 620 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 66206.2948717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 66206.29487179
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 66206.29487179 with a remainder of 3.8e-08.
