We divide 3399631 by 310
We want to divide 3399631 by 310.

Step 1:
310 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 310

Step 2:
310 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 310

Step 3:
339 divided by 310 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 310 away from 339, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 310

Moving on to step 4:
310 can be fit into 299 0 times, resulting in a remainder of 299.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 299 after subtracting 0 from 299.
Bring next digit (6) of the dividend behind the 299 and repeat the process: 2996 / 310

Step 5:
2996 divided by 310 is 9 with a remainder of 206.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 2790 from 2996 to get 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 310

Going ahead to step 6:
310 can be fit into 2063 6 times, resulting in a remainder of 203.
Use 6 as the next digit of our solution. 
Result so far: 1096.0
If we take 1860 away from 2063, we end up with 203.
Include the next digit (1) from the dividend after 203, then repeat: 2031 / 310

On to step 7:
310 goes into 2031 6 times with a remainder of 171.
The next digit of our result is 6. 
Result so far: 10966.0
The remainder is 171 after subtracting 1860 from 2031.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 8:
When dividing 1710 by 310, we get 5 with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 10966.5
Subtract 1550 from 1710 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 9:
310 goes into 1600 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10966.55
Subtracting 1550 from 1600 leaves us 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.

The final outcome is 10966.55, with a leftover of 0.05.
