180138 ÷ 70 
We want to figure out the number of times 180138 can be divided by 70.

Step 1:
70 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 70

Step 2:
18 divided by 70 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 70

Let's proceed to step 3:
70 goes into 180 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 140 from 180 and we're left with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 70

Step 4:
The number 70 fits into 401 5 times, leaving a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 51 after subtracting 350 from 401.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 70

Step 5:
When dividing 513 by 70, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 257.0
If we take 490 away from 513, we end up with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 70

Going ahead to step 6:
The number 70 fits into 238 3 times, leaving a remainder of 28.
The next digit of our result is 3. 
Result so far: 2573.0
If we take 210 away from 238, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
70 goes into 280 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 2573.4
If we take 280 away from 280, 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.

Step 8:
When dividing 0 by 70, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2573.4
Subtracting 0 from 0 leaves us 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.

Step 9:
The number 70 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2573.4
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.

The final outcome is 2573.4, with a leftover of 0.0.
