6437784 ÷ 312 
We want to divide 6437784 by 312.

Advancing to step 1:
The number 312 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 312

Going ahead to step 2:
64 divided by 312 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 312

Let's proceed to step 3:
If we divide 643 by 312, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 624 from 643 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 312

Moving on to step 4:
312 can be fit into 197 0 times, resulting in a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 197 and we're left with 197.
Append the next digit (7) from the dividend to 197 and continue with: 1977 / 312

Going ahead to step 5:
1977 divided by 312 is 6 with a remainder of 105.
Write down 6 as next digit of the result. 
Result so far: 206.0
Deduct 1872 from 1977 and we're left with 105.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 312

Advancing to step 6:
312 can be fit into 1058 3 times, resulting in a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 2063.0
Deduct 936 from 1058 and we're left with 122.
Take the next digit (4) from the dividend and append it to 122, then repeat: 1224 / 312

Advancing to step 7:
1224 divided by 312 is 3 with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 20633.0
Subtract 936 from 1224 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 8:
If we divide 2880 by 312, we get 9 and a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 20633.9
Subtract 2808 from 2880 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
720 divided by 312 is 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 20633.92
Deduct 624 from 720 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
312 goes into 960 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 20633.923
Subtracting 936 from 960 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
312 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 20633.923
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
312 goes into 2400 7 times with a remainder of 216.
Write down 7 as next digit of the result. 
Result so far: 20633.92307
If we take 2184 away from 2400, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 13:
The number 312 fits into 2160 6 times, leaving a remainder of 288.
The next digit of our result is 6. 
Result so far: 20633.923076
Subtracting 1872 from 2160 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 14:
312 goes into 2880 9 times with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 20633.9230769
The remainder is 72 after subtracting 2808 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 312 fits into 720 2 times, leaving a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 20633.92307692
The remainder is 96 after subtracting 624 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 20633.92307692, and the remainder is 9.6e-08.
