142670 ÷ 48 
We want to divide 142670 by 48.

Step 1:
If we divide 1 by 48, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 48

Advancing to step 2:
48 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 48

Moving on to step 3:
48 goes into 142 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 46 after subtracting 96 from 142.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 48

Step 4:
If we divide 466 by 48, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 432 away from 466, we end up with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 48

On to step 5:
48 can be fit into 347 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 297.0
If we take 336 away from 347, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 48

Step 6:
48 goes into 110 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2972.0
The remainder is 14 after subtracting 96 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 48, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2972.2
Subtract 96 from 140 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
If we divide 440 by 48, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 2972.29
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
48 goes into 80 1 times with a remainder of 32.
The next digit of our result is 1. 
Result so far: 2972.291
Deduct 48 from 80 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 48, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 2972.2916
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
If we divide 320 by 48, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2972.29166
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 2972.29166, with a leftover of 3.2e-05.
