We look at the division of 42893373 by 486 
We're looking to find how many times 486 goes into 42893373.

Going ahead to step 1:
If we divide 4 by 486, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 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
Subtract 0 from 42 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 486

Let's proceed to step 3:
If we divide 428 by 486, we get 0 and a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Fetch the next digit (9) from the dividend, attach it to 428 and continue: 4289 / 486

Advancing to step 4:
4289 divided by 486 is 8 with a remainder of 401.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 3888 from 4289 and we're left with 401.
Include the next digit (3) from the dividend after 401, then repeat: 4013 / 486

Let's proceed to step 5:
486 goes into 4013 8 times with a remainder of 125.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
The remainder is 125 after subtracting 3888 from 4013.
Fetch the next digit (3) from the dividend, attach it to 125 and continue: 1253 / 486

Advancing to step 6:
486 goes into 1253 2 times with a remainder of 281.
Write down 2 as next digit of the result. 
Result so far: 882.0
Deduct 972 from 1253 and we're left with 281.
Take the next digit (7) from the dividend and append it to 281, then repeat: 2817 / 486

Let's proceed to step 7:
The number 486 fits into 2817 5 times, leaving a remainder of 387.
Put 5 as the next digit of the answer. 
Result so far: 8825.0
If we subtract 2430 from 2817, we get 387.
Fetch the next digit (3) from the dividend, attach it to 387 and continue: 3873 / 486

On to step 8:
486 can be fit into 3873 7 times, resulting in a remainder of 471.
Record the quotient 7 as the next digit in the result. 
Result so far: 88257.0
Subtracting 3402 from 3873 leaves us with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 9:
486 goes into 4710 9 times with a remainder of 336.
Write down 9 as next digit of the result. 
Result so far: 88257.9
Deduct 4374 from 4710 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
486 goes into 3360 6 times with a remainder of 444.
Write down 6 as next digit of the result. 
Result so far: 88257.96
If we take 2916 away from 3360, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 11:
486 goes into 4440 9 times with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 88257.969
If we subtract 4374 from 4440, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
If we divide 660 by 486, we get 1 and a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 88257.9691
If we subtract 486 from 660, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 13:
486 can be fit into 1740 3 times, resulting in a remainder of 282.
The next digit of our result is 3. 
Result so far: 88257.96913
Subtract 1458 from 1740 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 14:
486 goes into 2820 5 times with a remainder of 390.
The next digit of our result is 5. 
Result so far: 88257.969135
Deduct 2430 from 2820 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 15:
486 can be fit into 3900 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 88257.9691358
If we subtract 3888 from 3900, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
120 divided by 486 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 88257.9691358
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 88257.9691358 with a remainder of 1.2e-07.
