We divide 638930 by 42
Our goal is to divide 638930 by 42.

Moving on to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 42

Going ahead to step 2:
63 divided by 42 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 63, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 42

Step 3:
When dividing 218 by 42, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 8 after subtracting 210 from 218.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 42

Going ahead to step 4:
If we divide 89 by 42, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtracting 84 from 89 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 42

Going ahead to step 5:
The number 42 fits into 53 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1521.0
Subtracting 42 from 53 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 42

Advancing to step 6:
110 divided by 42 is 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 15212.0
If we subtract 84 from 110, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 15212.6
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 15212.61
If we take 42 away from 80, we end up 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.

On to step 9:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 15212.619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15212.619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 15212.61904
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 15212.619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
The number 42 fits into 260 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 15212.6190476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 15212.61904761
Deduct 42 from 80 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.

The quotient of the division is 15212.61904761, and the remainder is 3.8e-08.
