870066 ÷ 61 
Our goal is to divide 870066 by 61.

Advancing to step 1:
The number 61 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 61

Step 2:
87 divided by 61 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 61 from 87, we get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 61

Going ahead to step 3:
When dividing 260 by 61, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 244 from 260, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 61

On to step 4:
The number 61 fits into 160 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Subtract 122 from 160 to get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 61

Going ahead to step 5:
386 divided by 61 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1426.0
The remainder is 20 after subtracting 366 from 386.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 61

Moving on to step 6:
When dividing 206 by 61, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 14263.0
If we take 183 away from 206, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 61, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 14263.3
Subtracting 183 from 230 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 8:
470 divided by 61 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 14263.37
Subtract 427 from 470 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
61 can be fit into 430 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 14263.377
Subtract 427 from 430 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 14263.377 with a remainder of 0.0003.
