We look at the division of 643102 by 74 
Our goal is to divide 643102 by 74.

Moving on to step 1:
6 divided by 74 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 74

Step 2:
74 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 74

Going ahead to step 3:
643 divided by 74 is 8 with a remainder of 51.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 592 from 643, we get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 74

Advancing to step 4:
74 goes into 511 6 times with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 67 after subtracting 444 from 511.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 74

On to step 5:
74 goes into 670 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we take 666 away from 670, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 74

On to step 6:
74 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 8690.0
If we subtract 0 from 42, 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.

On to step 7:
The number 74 fits into 420 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 8690.5
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
74 can be fit into 500 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 8690.56
Subtracting 444 from 500 leaves us 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.

Going ahead to step 9:
74 goes into 560 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 8690.567
If we take 518 away from 560, 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.

Step 10:
74 can be fit into 420 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 8690.5675
The remainder is 50 after subtracting 370 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
500 divided by 74 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 8690.56756
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
74 goes into 560 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 8690.567567
If we take 518 away from 560, 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.

On to step 13:
74 can be fit into 420 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 8690.5675675
Deduct 370 from 420 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
The number 74 fits into 500 6 times, leaving a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 8690.56756756
Deduct 444 from 500 and we're left 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.

The quotient of the division is 8690.56756756, and the remainder is 5.6e-08.
