149950 ÷ 70 
We want to figure out the number of times 149950 can be divided by 70.

Step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 70

Advancing to step 2:
The number 70 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 70

Let's proceed to step 3:
When dividing 149 by 70, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 140 from 149 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 70

Let's proceed to step 4:
70 goes into 99 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 29 after subtracting 70 from 99.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 70

Advancing to step 5:
70 can be fit into 295 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 280 away from 295, we end up with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 70

Advancing to step 6:
70 goes into 150 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2142.0
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 2142.1
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 70 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 2142.14
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 2142.142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
70 goes into 600 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 2142.1428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2142.14285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 2142.142857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2142.1428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 2142.14285714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 2142.14285714 and a remainder of 2e-08.
