We're dividing 42381342 by 486 
Our goal is to divide 42381342 by 486.

Step 1:
If we divide 4 by 486, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 486

Moving on to step 2:
The number 486 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 486

Moving on to step 3:
When dividing 423 by 486, we get 0 with a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Append the next digit (8) from the dividend to 423 and continue with: 4238 / 486

Let's proceed to step 4:
The number 486 fits into 4238 8 times, leaving a remainder of 350.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 3888 from 4238 leaves us with 350.
Fetch the next digit (1) from the dividend, attach it to 350 and continue: 3501 / 486

Let's proceed to step 5:
When dividing 3501 by 486, we get 7 with a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 3402 from 3501 leaves us with 99.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 486

Advancing to step 6:
486 can be fit into 993 2 times, resulting in a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 872.0
If we subtract 972 from 993, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 486

Step 7:
486 can be fit into 214 0 times, resulting in a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 8720.0
Subtracting 0 from 214 leaves us with 214.
Take the next digit (2) from the dividend and append it to 214, then repeat: 2142 / 486

Step 8:
When dividing 2142 by 486, we get 4 with a remainder of 198.
Use 4 as the next digit of our solution. 
Result so far: 87204.0
The remainder is 198 after subtracting 1944 from 2142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
486 can be fit into 1980 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 87204.4
If we take 1944 away from 1980, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
360 divided by 486 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 87204.4
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
When dividing 3600 by 486, we get 7 with a remainder of 198.
Write down 7 as next digit of the result. 
Result so far: 87204.407
If we take 3402 away from 3600, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 12:
When dividing 1980 by 486, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 87204.4074
Deduct 1944 from 1980 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
486 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 87204.4074
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
The number 486 fits into 3600 7 times, leaving a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 87204.407407
If we take 3402 away from 3600, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 15:
When dividing 1980 by 486, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 87204.4074074
The remainder is 36 after subtracting 1944 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 16:
The number 486 fits into 360 0 times, leaving a remainder of 360.
The next digit of our result is 0. 
Result so far: 87204.4074074
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 87204.4074074, and the remainder is 3.6e-07.
