Going ahead to step 4:
970 can be fit into 3042 3 times, resulting in a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2910 from 3042 and we're left with 132.
Fetch the next digit (9) from the dividend, attach it to 132 and continue: 1329 / 970

Moving on to step 5:
1329 divided by 970 is 1 with a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 970 from 1329, we get 359.
Bring next digit (8) of the dividend behind the 359 and repeat the process: 3598 / 970

Moving on to step 6:
970 can be fit into 3598 3 times, resulting in a remainder of 688.
The number 3 becomes the next digit in our result. 
Result so far: 313.0
The remainder is 688 after subtracting 2910 from 3598.
Fetch the next digit (9) from the dividend, attach it to 688 and continue: 6889 / 970

Going ahead to step 7:
When dividing 6889 by 970, we get 7 with a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 3137.0
Subtracting 6790 from 6889 leaves us with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 970

Going ahead to step 8:
If we divide 991 by 970, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 31371.0
Subtract 970 from 991 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
210 divided by 970 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 31371.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
2100 divided by 970 is 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 31371.02
If we subtract 1940 from 2100, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
The number 970 fits into 1600 1 times, leaving a remainder of 630.
The next digit of our result is 1. 
Result so far: 31371.021
Subtracting 970 from 1600 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 12:
The number 970 fits into 6300 6 times, leaving a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 31371.0216
If we take 5820 away from 6300, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
970 goes into 4800 4 times with a remainder of 920.
Use 4 as the next digit of our solution. 
Result so far: 31371.02164
The remainder is 920 after subtracting 3880 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Moving on to step 14:
970 goes into 9200 9 times with a remainder of 470.
The next digit of our result is 9. 
Result so far: 31371.021649
If we take 8730 away from 9200, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 15:
970 can be fit into 4700 4 times, resulting in a remainder of 820.
Put 4 as the next digit of the answer. 
Result so far: 31371.0216494
If we take 3880 away from 4700, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 16:
When dividing 8200 by 970, we get 8 with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 31371.02164948
Subtract 7760 from 8200 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 31371.02164948 with a remaining 4.4e-07.
