215730 ÷ 70 
We want to figure out the number of times 215730 can be divided by 70.

Moving on to step 1:
The number 70 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 70

Step 2:
70 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 70

Moving on to step 3:
The number 70 fits into 215 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 210 from 215 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 70

Advancing to step 4:
70 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 70

Advancing to step 5:
When dividing 573 by 70, we get 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 308.0
The remainder is 13 after subtracting 560 from 573.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 70

Let's proceed to step 6:
70 can be fit into 130 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 3081.0
The remainder is 60 after subtracting 70 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3081.8
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.

Step 8:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 3081.85
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 3081.857
Subtracting 490 from 500 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.

Let's proceed to step 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 3081.8571
Subtracting 70 from 100 leaves us 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.

Moving on to step 11:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3081.85714
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.

Going ahead to step 12:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 3081.857142
If we take 140 away from 200, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
When dividing 600 by 70, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3081.8571428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
400 divided by 70 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3081.85714285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 3081.85714285 with a remaining 5e-08.
