We look at the division of 3970 by 47 
Let's see how many times 47 fits into 3970.

Advancing to step 1:
If we divide 3 by 47, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 47

On to step 2:
47 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 47

Advancing to step 3:
397 divided by 47 is 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 376 from 397, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 47

Going ahead to step 4:
47 can be fit into 210 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 188 from 210, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 5:
47 can be fit into 220 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.4
Subtract 188 from 220 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 6:
The number 47 fits into 320 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 84.46
Subtract 282 from 320 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
When dividing 380 by 47, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 84.468
Subtracting 376 from 380 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 47, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 84.468
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
400 divided by 47 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 84.46808
If we subtract 376 from 400, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
240 divided by 47 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 84.468085
Deduct 235 from 240 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
47 can be fit into 50 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 84.4680851
The remainder is 3 after subtracting 47 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
47 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 84.4680851
Deduct 0 from 30 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.

The final outcome is 84.4680851, with a leftover of 3e-08.
