We look at the division of 12376759 by 816 
Our goal is to divide 12376759 by 816.

Let's proceed to step 1:
The number 816 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 816

Going ahead to step 2:
If we divide 12 by 816, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 816

Moving on to step 3:
816 can be fit into 123 0 times, resulting in a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 123, we end up with 123.
Bring next digit (7) of the dividend behind the 123 and repeat the process: 1237 / 816

Going ahead to step 4:
1237 divided by 816 is 1 with a remainder of 421.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 816 from 1237 leaves us with 421.
Fetch the next digit (6) from the dividend, attach it to 421 and continue: 4216 / 816

Let's proceed to step 5:
816 goes into 4216 5 times with a remainder of 136.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 4080 from 4216 leaves us with 136.
Append the next digit (7) from the dividend to 136 and continue with: 1367 / 816

Let's proceed to step 6:
1367 divided by 816 is 1 with a remainder of 551.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Deduct 816 from 1367 and we're left with 551.
Fetch the next digit (5) from the dividend, attach it to 551 and continue: 5515 / 816

Step 7:
816 can be fit into 5515 6 times, resulting in a remainder of 619.
Write down 6 as next digit of the result. 
Result so far: 1516.0
The remainder is 619 after subtracting 4896 from 5515.
Take the next digit (9) from the dividend and append it to 619, then repeat: 6199 / 816

Going ahead to step 8:
If we divide 6199 by 816, we get 7 and a remainder of 487.
Put 7 as the next digit of the answer. 
Result so far: 15167.0
Subtracting 5712 from 6199 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Step 9:
If we divide 4870 by 816, we get 5 and a remainder of 790.
Put 5 as the next digit of the answer. 
Result so far: 15167.5
Deduct 4080 from 4870 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Let's proceed to step 10:
816 goes into 7900 9 times with a remainder of 556.
Record the quotient 9 as the next digit in the result. 
Result so far: 15167.59
If we take 7344 away from 7900, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 11:
816 goes into 5560 6 times with a remainder of 664.
The next digit of our result is 6. 
Result so far: 15167.596
Subtract 4896 from 5560 to get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 12:
816 can be fit into 6640 8 times, resulting in a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 15167.5968
Deduct 6528 from 6640 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 13:
If we divide 1120 by 816, we get 1 and a remainder of 304.
Put 1 as the next digit of the answer. 
Result so far: 15167.59681
The remainder is 304 after subtracting 816 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 14:
When dividing 3040 by 816, we get 3 with a remainder of 592.
Put 3 as the next digit of the answer. 
Result so far: 15167.596813
Subtract 2448 from 3040 to get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 15:
If we divide 5920 by 816, we get 7 and a remainder of 208.
Put 7 as the next digit of the answer. 
Result so far: 15167.5968137
Subtracting 5712 from 5920 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 16:
When dividing 2080 by 816, we get 2 with a remainder of 448.
The number 2 becomes the next digit in our result. 
Result so far: 15167.59681372
Subtracting 1632 from 2080 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

After the division, we end up with 15167.59681372 and a remainder of 4.48e-07.
