61711578 ÷ 36 
We want to figure out the number of times 61711578 can be divided by 36.

Step 1:
6 divided by 36 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 36

Step 2:
36 goes into 61 1 times with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 36 from 61 to get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 36

Step 3:
36 can be fit into 257 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 252 from 257, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 36

Advancing to step 4:
The number 36 fits into 51 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
Subtracting 36 from 51 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 36

Step 5:
151 divided by 36 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 1714.0
Deduct 144 from 151 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 36

On to step 6:
If we divide 75 by 36, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 17142.0
If we take 72 away from 75, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 36

On to step 7:
36 can be fit into 37 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 171421.0
The remainder is 1 after subtracting 36 from 37.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 36

Step 8:
36 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 1714210.0
Subtract 0 from 18 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 36, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1714210.5
Deduct 180 from 180 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
36 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1714210.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 36 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1714210.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1714210.5 with a remainder of 0.0.
