We're dividing 142891 by 35 
We want to figure out the number of times 142891 can be divided by 35.

Let's proceed to step 1:
When dividing 1 by 35, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 35

Let's proceed to step 2:
If we divide 14 by 35, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 35

Moving on to step 3:
35 goes into 142 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 140 from 142 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 35

Step 4:
35 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 28, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 35

Let's proceed to step 5:
35 can be fit into 289 8 times, resulting in a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 408.0
Subtracting 280 from 289 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 35

Going ahead to step 6:
When dividing 91 by 35, we get 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 4082.0
Subtract 70 from 91 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
35 can be fit into 210 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 4082.6
Subtract 210 from 210 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.

Advancing to step 8:
If we divide 0 by 35, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4082.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 35, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4082.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4082.6, with a leftover of 0.0.
