We divide 39706391 by 312
Our goal is to divide 39706391 by 312.

On to step 1:
312 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 312

Moving on to step 2:
312 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 312

Let's proceed to step 3:
When dividing 397 by 312, we get 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 85 after subtracting 312 from 397.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 312

Advancing to step 4:
When dividing 850 by 312, we get 2 with a remainder of 226.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 226 after subtracting 624 from 850.
Take the next digit (6) from the dividend and append it to 226, then repeat: 2266 / 312

On to step 5:
When dividing 2266 by 312, we get 7 with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtracting 2184 from 2266 leaves us with 82.
Include the next digit (3) from the dividend after 82, then repeat: 823 / 312

Moving on to step 6:
The number 312 fits into 823 2 times, leaving a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 1272.0
Deduct 624 from 823 and we're left with 199.
Bring next digit (9) of the dividend behind the 199 and repeat the process: 1999 / 312

Let's proceed to step 7:
If we divide 1999 by 312, we get 6 and a remainder of 127.
The next digit of our result is 6. 
Result so far: 12726.0
If we subtract 1872 from 1999, we get 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 312

Going ahead to step 8:
When dividing 1271 by 312, we get 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 127264.0
Subtract 1248 from 1271 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
When dividing 230 by 312, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 127264.0
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 10:
312 goes into 2300 7 times with a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 127264.07
Deduct 2184 from 2300 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
312 goes into 1160 3 times with a remainder of 224.
The next digit of our result is 3. 
Result so far: 127264.073
If we take 936 away from 1160, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
When dividing 2240 by 312, we get 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 127264.0737
Subtract 2184 from 2240 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
The number 312 fits into 560 1 times, leaving a remainder of 248.
The next digit of our result is 1. 
Result so far: 127264.07371
Subtract 312 from 560 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 14:
The number 312 fits into 2480 7 times, leaving a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 127264.073717
Deduct 2184 from 2480 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 15:
If we divide 2960 by 312, we get 9 and a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 127264.0737179
Subtract 2808 from 2960 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 16:
When dividing 1520 by 312, we get 4 with a remainder of 272.
Use 4 as the next digit of our solution. 
Result so far: 127264.07371794
If we take 1248 away from 1520, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 127264.07371794, and the remainder is 2.72e-07.
