42212601 divided by 486 
Let's see how many times 486 fits into 42212601.

Going ahead to step 1:
486 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 486

Advancing to step 2:
42 divided by 486 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 486

Moving on to step 3:
422 divided by 486 is 0 with a remainder of 422.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 422, we end up with 422.
Append the next digit (1) from the dividend to 422 and continue with: 4221 / 486

On to step 4:
486 goes into 4221 8 times with a remainder of 333.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 3888 from 4221 to get 333.
Append the next digit (2) from the dividend to 333 and continue with: 3332 / 486

On to step 5:
When dividing 3332 by 486, we get 6 with a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 2916 away from 3332, we end up with 416.
Bring next digit (6) of the dividend behind the 416 and repeat the process: 4166 / 486

Going ahead to step 6:
4166 divided by 486 is 8 with a remainder of 278.
The next digit of our result is 8. 
Result so far: 868.0
If we take 3888 away from 4166, we end up with 278.
Bring next digit (0) of the dividend behind the 278 and repeat the process: 2780 / 486

Going ahead to step 7:
When dividing 2780 by 486, we get 5 with a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 8685.0
Subtracting 2430 from 2780 leaves us with 350.
Fetch the next digit (1) from the dividend, attach it to 350 and continue: 3501 / 486

Moving on to step 8:
486 can be fit into 3501 7 times, resulting in a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 86857.0
If we take 3402 away from 3501, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
486 goes into 990 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 86857.2
Subtracting 972 from 990 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
When dividing 180 by 486, we get 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 86857.2
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
When dividing 1800 by 486, we get 3 with a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 86857.203
Subtract 1458 from 1800 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 12:
When dividing 3420 by 486, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 86857.2037
If we subtract 3402 from 3420, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
180 divided by 486 is 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 86857.2037
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
The number 486 fits into 1800 3 times, leaving a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 86857.203703
Subtracting 1458 from 1800 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 15:
When dividing 3420 by 486, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 86857.2037037
If we take 3402 away from 3420, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
When dividing 180 by 486, we get 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 86857.2037037
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 86857.2037037 with a remainder of 1.8e-07.
