61066030 divided by 870 
Our goal is to divide 61066030 by 870.

Moving on to step 1:
870 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 870

On to step 2:
870 can be fit into 61 0 times, resulting in a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 870

On to step 3:
870 can be fit into 610 0 times, resulting in a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 610 to get 610.
Bring next digit (6) of the dividend behind the 610 and repeat the process: 6106 / 870

Advancing to step 4:
If we divide 6106 by 870, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 16 after subtracting 6090 from 6106.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 870

Step 5:
The number 870 fits into 166 0 times, leaving a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 166, we get 166.
Take the next digit (0) from the dividend and append it to 166, then repeat: 1660 / 870

Let's proceed to step 6:
If we divide 1660 by 870, we get 1 and a remainder of 790.
The number 1 becomes the next digit in our result. 
Result so far: 701.0
Subtracting 870 from 1660 leaves us with 790.
Include the next digit (3) from the dividend after 790, then repeat: 7903 / 870

Moving on to step 7:
870 can be fit into 7903 9 times, resulting in a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 7019.0
Subtracting 7830 from 7903 leaves us with 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 870

Let's proceed to step 8:
730 divided by 870 is 0 with a remainder of 730.
Record the quotient 0 as the next digit in the result. 
Result so far: 70190.0
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 9:
870 goes into 7300 8 times with a remainder of 340.
Put 8 as the next digit of the answer. 
Result so far: 70190.8
Subtracting 6960 from 7300 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
If we divide 3400 by 870, we get 3 and a remainder of 790.
Write down 3 as next digit of the result. 
Result so far: 70190.83
Subtract 2610 from 3400 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 11:
870 goes into 7900 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 70190.839
Subtracting 7830 from 7900 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
700 divided by 870 is 0 with a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 70190.839
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 13:
The number 870 fits into 7000 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 70190.83908
If we subtract 6960 from 7000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
When dividing 400 by 870, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 70190.83908
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
870 can be fit into 4000 4 times, resulting in a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 70190.8390804
Subtract 3480 from 4000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
The number 870 fits into 5200 5 times, leaving a remainder of 850.
The next digit of our result is 5. 
Result so far: 70190.83908045
If we take 4350 away from 5200, we end up with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

After the division, we end up with 70190.83908045 and a remainder of 8.5e-07.
