We're dividing 42898387 by 10 
We want to figure out the number of times 42898387 can be divided by 10.

Step 1:
If we divide 4 by 10, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 10

Advancing to step 2:
42 divided by 10 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 2 after subtracting 40 from 42.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 10

Let's proceed to step 3:
10 goes into 28 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 20 from 28, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 10

Going ahead to step 4:
When dividing 89 by 10, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we subtract 80 from 89, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 10

Advancing to step 5:
The number 10 fits into 98 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 4289.0
If we subtract 90 from 98, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 10

Moving on to step 6:
When dividing 83 by 10, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 42898.0
Subtracting 80 from 83 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 10

Advancing to step 7:
The number 10 fits into 38 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 428983.0
Subtracting 30 from 38 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 10

Moving on to step 8:
10 goes into 87 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 4289838.0
Deduct 80 from 87 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
70 divided by 10 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 4289838.7
The remainder is 0 after subtracting 70 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4289838.7
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4289838.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4289838.7 with a remaining 0.0.
