If we subtract 0 from 3, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 870

Moving on to step 2:
36 divided by 870 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 870

Advancing to step 3:
If we divide 366 by 870, we get 0 and a remainder of 366.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 366 to get 366.
Append the next digit (3) from the dividend to 366 and continue with: 3663 / 870

Moving on to step 4:
When dividing 3663 by 870, we get 4 with a remainder of 183.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3480 from 3663 to get 183.
Grab the next digit (9) from the dividend, add it to 183, then carry on: 1839 / 870

On to step 5:
870 can be fit into 1839 2 times, resulting in a remainder of 99.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 1740 from 1839, we get 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 870

On to step 6:
991 divided by 870 is 1 with a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
Subtract 870 from 991 to get 121.
Take the next digit (6) from the dividend and append it to 121, then repeat: 1216 / 870

Advancing to step 7:
870 can be fit into 1216 1 times, resulting in a remainder of 346.
Write down 1 as next digit of the result. 
Result so far: 4211.0
Subtracting 870 from 1216 leaves us with 346.
Grab the next digit (7) from the dividend, add it to 346, then carry on: 3467 / 870

Step 8:
870 can be fit into 3467 3 times, resulting in a remainder of 857.
Use 3 as the next digit of our solution. 
Result so far: 42113.0
If we subtract 2610 from 3467, we get 857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

On to step 9:
8570 divided by 870 is 9 with a remainder of 740.
The next digit of our result is 9. 
Result so far: 42113.9
If we subtract 7830 from 8570, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 10:
870 goes into 7400 8 times with a remainder of 440.
The next digit of our result is 8. 
Result so far: 42113.98
If we subtract 6960 from 7400, we 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.

Step 11:
If we divide 4400 by 870, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 42113.985
Deduct 4350 from 4400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
870 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 42113.985
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
The number 870 fits into 5000 5 times, leaving a remainder of 650.
The number 5 becomes the next digit in our result. 
Result so far: 42113.98505
If we take 4350 away from 5000, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 14:
6500 divided by 870 is 7 with a remainder of 410.
The next digit of our result is 7. 
Result so far: 42113.985057
Deduct 6090 from 6500 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 15:
4100 divided by 870 is 4 with a remainder of 620.
Put 4 as the next digit of the answer. 
Result so far: 42113.9850574
Deduct 3480 from 4100 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 16:
870 goes into 6200 7 times with a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 42113.98505747
The remainder is 110 after subtracting 6090 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 42113.98505747 and a remainder of 1.1e-07.
