Let's divide 64328051 by 646
Our goal is to divide 64328051 by 646.

Moving on to step 1:
646 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 646

Advancing to step 2:
If we divide 64 by 646, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 646

Let's proceed to step 3:
646 can be fit into 643 0 times, resulting in a remainder of 643.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 643, we get 643.
Include the next digit (2) from the dividend after 643, then repeat: 6432 / 646

Step 4:
When dividing 6432 by 646, we get 9 with a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 5814 from 6432, we get 618.
Take the next digit (8) from the dividend and append it to 618, then repeat: 6188 / 646

Moving on to step 5:
The number 646 fits into 6188 9 times, leaving a remainder of 374.
Write down 9 as next digit of the result. 
Result so far: 99.0
Deduct 5814 from 6188 and we're left with 374.
Bring next digit (0) of the dividend behind the 374 and repeat the process: 3740 / 646

Step 6:
The number 646 fits into 3740 5 times, leaving a remainder of 510.
Write down 5 as next digit of the result. 
Result so far: 995.0
If we take 3230 away from 3740, we end up with 510.
Take the next digit (5) from the dividend and append it to 510, then repeat: 5105 / 646

Let's proceed to step 7:
5105 divided by 646 is 7 with a remainder of 583.
Write down 7 as next digit of the result. 
Result so far: 9957.0
If we take 4522 away from 5105, we end up with 583.
Bring next digit (1) of the dividend behind the 583 and repeat the process: 5831 / 646

Advancing to step 8:
646 can be fit into 5831 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 99579.0
Deduct 5814 from 5831 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
646 can be fit into 170 0 times, resulting in a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 99579.0
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 646 fits into 1700 2 times, leaving a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 99579.02
If we take 1292 away from 1700, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 11:
When dividing 4080 by 646, we get 6 with a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 99579.026
The remainder is 204 after subtracting 3876 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
646 can be fit into 2040 3 times, resulting in a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 99579.0263
The remainder is 102 after subtracting 1938 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 13:
When dividing 1020 by 646, we get 1 with a remainder of 374.
Write down 1 as next digit of the result. 
Result so far: 99579.02631
If we subtract 646 from 1020, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 14:
When dividing 3740 by 646, we get 5 with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 99579.026315
If we subtract 3230 from 3740, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 15:
646 can be fit into 5100 7 times, resulting in a remainder of 578.
Put 7 as the next digit of the answer. 
Result so far: 99579.0263157
Deduct 4522 from 5100 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 16:
5780 divided by 646 is 8 with a remainder of 612.
Use 8 as the next digit of our solution. 
Result so far: 99579.02631578
If we take 5168 away from 5780, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

After the division, we end up with 99579.02631578 and a remainder of 6.12e-07.
