40448837 ÷ 312 
We're looking to find how many times 312 goes into 40448837.

Advancing to step 1:
If we divide 4 by 312, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 312

Going ahead to step 2:
The number 312 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 312

Going ahead to step 3:
The number 312 fits into 404 1 times, leaving a remainder of 92.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 312 from 404, we get 92.
Take the next digit (4) from the dividend and append it to 92, then repeat: 924 / 312

Let's proceed to step 4:
312 can be fit into 924 2 times, resulting in a remainder of 300.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 300 after subtracting 624 from 924.
Append the next digit (8) from the dividend to 300 and continue with: 3008 / 312

Step 5:
If we divide 3008 by 312, we get 9 and a remainder of 200.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Deduct 2808 from 3008 and we're left with 200.
Grab the next digit (8) from the dividend, add it to 200, then carry on: 2008 / 312

Advancing to step 6:
If we divide 2008 by 312, we get 6 and a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 1296.0
Deduct 1872 from 2008 and we're left with 136.
Bring next digit (3) of the dividend behind the 136 and repeat the process: 1363 / 312

Step 7:
312 goes into 1363 4 times with a remainder of 115.
Put 4 as the next digit of the answer. 
Result so far: 12964.0
Subtracting 1248 from 1363 leaves us with 115.
Append the next digit (7) from the dividend to 115 and continue with: 1157 / 312

Step 8:
When dividing 1157 by 312, we get 3 with a remainder of 221.
The number 3 becomes the next digit in our result. 
Result so far: 129643.0
Subtracting 936 from 1157 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
2210 divided by 312 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 129643.7
Deduct 2184 from 2210 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
If we divide 260 by 312, we get 0 and a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 129643.7
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
2600 divided by 312 is 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 129643.708
If we take 2496 away from 2600, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
The number 312 fits into 1040 3 times, leaving a remainder of 104.
The next digit of our result is 3. 
Result so far: 129643.7083
If we subtract 936 from 1040, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 13:
1040 divided by 312 is 3 with a remainder of 104.
Put 3 as the next digit of the answer. 
Result so far: 129643.70833
Subtracting 936 from 1040 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 129643.70833, and the remainder is 0.000104.
