Moving on to step 1:
970 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 970

Going ahead to step 2:
20 divided by 970 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0

Moving on to step 3:
970 can be fit into 205 0 times, resulting in a remainder of 205.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 205 and we're left with 205.
Grab the next digit (0) from the dividend, add it to 205, then carry on: 2050 / 970

On to step 4:
970 goes into 2050 2 times with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1940 from 2050, we get 110.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 970

Going ahead to step 5:
1105 divided by 970 is 1 with a remainder of 135.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 135 after subtracting 970 from 1105.
Take the next digit (2) from the dividend and append it to 135, then repeat: 1352 / 970

Step 6:
When dividing 1352 by 970, we get 1 with a remainder of 382.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtracting 970 from 1352 leaves us with 382.
Include the next digit (3) from the dividend after 382, then repeat: 3823 / 970

Step 7:
When dividing 3823 by 970, we get 3 with a remainder of 913.
Use 3 as the next digit of our solution. 
Result so far: 2113.0
Subtracting 2910 from 3823 leaves us with 913.
Append the next digit (1) from the dividend to 913 and continue with: 9131 / 970

Advancing to step 8:
When dividing 9131 by 970, we get 9 with a remainder of 401.
Write down 9 as next digit of the result. 
Result so far: 21139.0
Subtract 8730 from 9131 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 9:
When dividing 4010 by 970, we get 4 with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 21139.4
Subtracting 3880 from 4010 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
1300 divided by 970 is 1 with a remainder of 330.
The next digit of our result is 1. 
Result so far: 21139.41
If we take 970 away from 1300, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 11:
When dividing 3300 by 970, we get 3 with a remainder of 390.
Use 3 as the next digit of our solution. 
Result so far: 21139.413
Subtracting 2910 from 3300 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 12:
If we divide 3900 by 970, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 21139.4134
The remainder is 20 after subtracting 3880 from 3900.
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 13:
200 divided by 970 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 21139.4134
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
The number 970 fits into 2000 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 21139.413402
If we take 1940 away from 2000, 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.

Going ahead to step 15:
If we divide 600 by 970, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 21139.413402
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 16:
If we divide 6000 by 970, we get 6 and a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 21139.41340206
If we subtract 5820 from 6000, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 21139.41340206 with a balance of 1.8e-07.
