3687166 divided by 764 
We want to divide 3687166 by 764.

On to step 1:
The number 764 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 764

On to step 2:
764 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 764

Moving on to step 3:
If we divide 368 by 764, we get 0 and a remainder of 368.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 368, we get 368.
Fetch the next digit (7) from the dividend, attach it to 368 and continue: 3687 / 764

Advancing to step 4:
If we divide 3687 by 764, we get 4 and a remainder of 631.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3056 away from 3687, we end up with 631.
Include the next digit (1) from the dividend after 631, then repeat: 6311 / 764

Going ahead to step 5:
If we divide 6311 by 764, we get 8 and a remainder of 199.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 6112 away from 6311, we end up with 199.
Include the next digit (6) from the dividend after 199, then repeat: 1996 / 764

Going ahead to step 6:
764 goes into 1996 2 times with a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 482.0
If we take 1528 away from 1996, we end up with 468.
Take the next digit (6) from the dividend and append it to 468, then repeat: 4686 / 764

Moving on to step 7:
764 goes into 4686 6 times with a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 4826.0
Deduct 4584 from 4686 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 8:
764 can be fit into 1020 1 times, resulting in a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 4826.1
The remainder is 256 after subtracting 764 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
2560 divided by 764 is 3 with a remainder of 268.
Record the quotient 3 as the next digit in the result. 
Result so far: 4826.13
Deduct 2292 from 2560 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 10:
764 can be fit into 2680 3 times, resulting in a remainder of 388.
Write down 3 as next digit of the result. 
Result so far: 4826.133
The remainder is 388 after subtracting 2292 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final outcome is 4826.133, with a leftover of 0.0388.
