61236415 divided by 310 
We're looking to find how many times 310 goes into 61236415.

On to step 1:
The number 310 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 310

Advancing to step 2:
310 goes into 61 0 times with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 310

Going ahead to step 3:
The number 310 fits into 612 1 times, leaving a remainder of 302.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 310 from 612, we get 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 310

Going ahead to step 4:
310 can be fit into 3023 9 times, resulting in a remainder of 233.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 2790 from 3023 to get 233.
Fetch the next digit (6) from the dividend, attach it to 233 and continue: 2336 / 310

Step 5:
310 goes into 2336 7 times with a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Deduct 2170 from 2336 and we're left with 166.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 310

On to step 6:
310 goes into 1664 5 times with a remainder of 114.
The next digit of our result is 5. 
Result so far: 1975.0
If we take 1550 away from 1664, we end up with 114.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 310

On to step 7:
If we divide 1141 by 310, we get 3 and a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 19753.0
Subtract 930 from 1141 to get 211.
Include the next digit (5) from the dividend after 211, then repeat: 2115 / 310

On to step 8:
310 goes into 2115 6 times with a remainder of 255.
Put 6 as the next digit of the answer. 
Result so far: 197536.0
If we subtract 1860 from 2115, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 9:
310 goes into 2550 8 times with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 197536.8
The remainder is 70 after subtracting 2480 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
310 can be fit into 700 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 197536.82
Subtract 620 from 700 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
If we divide 800 by 310, we get 2 and a remainder of 180.
The next digit of our result is 2. 
Result so far: 197536.822
If we take 620 away from 800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 197536.822, with a leftover of 0.018.
