We divide 638372 by 85
Let's see how many times 85 fits into 638372.

Let's proceed to step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 85

On to step 2:
If we divide 63 by 85, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 85

Step 3:
When dividing 638 by 85, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 595 from 638 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 85

Advancing to step 4:
The number 85 fits into 433 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 425 from 433, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 85

Step 5:
87 divided by 85 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 751.0
Deduct 85 from 87 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 85

Advancing to step 6:
85 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 7510.0
If we take 0 away from 22, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 85 fits into 220 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 7510.2
If we subtract 170 from 220, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
85 goes into 500 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7510.25
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
750 divided by 85 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 7510.258
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
85 goes into 700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 7510.2588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 7510.2588 with a remaining 0.0002.
