We look at the division of 515772 by 74 
We want to divide 515772 by 74.

Let's proceed to step 1:
When dividing 5 by 74, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 74

Let's proceed to step 2:
If we divide 51 by 74, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 74

Going ahead to step 3:
The number 74 fits into 515 6 times, leaving a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 444 from 515 to get 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 74

On to step 4:
74 goes into 717 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtracting 666 from 717 leaves us with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 74

Moving on to step 5:
517 divided by 74 is 6 with a remainder of 73.
Record the quotient 6 as the next digit in the result. 
Result so far: 696.0
Subtract 444 from 517 to get 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 74

Moving on to step 6:
74 can be fit into 732 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 6969.0
Subtract 666 from 732 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.

Moving on to step 7:
74 goes into 660 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 6969.8
Subtract 592 from 660 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.

On to step 8:
680 divided by 74 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 6969.89
If we take 666 away from 680, we end up 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.

On to step 9:
When dividing 140 by 74, we get 1 with a remainder of 66.
The next digit of our result is 1. 
Result so far: 6969.891
If we subtract 74 from 140, we 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.

Let's proceed to step 10:
660 divided by 74 is 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 6969.8918
The remainder is 68 after subtracting 592 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 11:
74 goes into 680 9 times with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 6969.89189
Subtract 666 from 680 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
The number 74 fits into 140 1 times, leaving a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 6969.891891
Subtract 74 from 140 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 13:
If we divide 660 by 74, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 6969.8918918
If we take 592 away from 660, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
74 goes into 680 9 times with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 6969.89189189
Deduct 666 from 680 and we're left 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.

The final outcome is 6969.89189189, with a leftover of 1.4e-08.
