Let's divide 6411686 by 310
We're looking to find how many times 310 goes into 6411686.

Going ahead to step 1:
310 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 310

Moving on to step 2:
If we divide 64 by 310, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 310

Going ahead to step 3:
When dividing 641 by 310, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 620 from 641 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 310

Step 4:
310 can be fit into 211 0 times, resulting in a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 211, we end up with 211.
Append the next digit (6) from the dividend to 211 and continue with: 2116 / 310

Step 5:
When dividing 2116 by 310, we get 6 with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 206.0
The remainder is 256 after subtracting 1860 from 2116.
Grab the next digit (8) from the dividend, add it to 256, then carry on: 2568 / 310

On to step 6:
2568 divided by 310 is 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 2068.0
If we take 2480 away from 2568, we end up with 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 310

Advancing to step 7:
886 divided by 310 is 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 20682.0
If we subtract 620 from 886, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 8:
The number 310 fits into 2660 8 times, leaving a remainder of 180.
Put 8 as the next digit of the answer. 
Result so far: 20682.8
Deduct 2480 from 2660 and we're left 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.

Going ahead to step 9:
310 goes into 1800 5 times with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 20682.85
Subtracting 1550 from 1800 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
When dividing 2500 by 310, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 20682.858
If we take 2480 away from 2500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
310 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 20682.858
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
310 goes into 2000 6 times with a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 20682.85806
Subtracting 1860 from 2000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
When dividing 1400 by 310, we get 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 20682.858064
Subtracting 1240 from 1400 leaves us with 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 14:
1600 divided by 310 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 20682.8580645
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.

Step 15:
If we divide 500 by 310, we get 1 and a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 20682.85806451
The remainder is 190 after subtracting 310 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 20682.85806451 with a balance of 1.9e-07.
