643826 divided by 97 
We want to divide 643826 by 97.

Let's proceed to step 1:
When dividing 6 by 97, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 97

Step 2:
If we divide 64 by 97, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 97

On to step 3:
97 goes into 643 6 times with a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 582 from 643, we get 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 97

On to step 4:
When dividing 618 by 97, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 36 after subtracting 582 from 618.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 97

On to step 5:
When dividing 362 by 97, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 663.0
Subtracting 291 from 362 leaves us with 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 97

Moving on to step 6:
97 goes into 716 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 6637.0
The remainder is 37 after subtracting 679 from 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
When dividing 370 by 97, we get 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 6637.3
If we take 291 away from 370, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 8:
If we divide 790 by 97, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 6637.38
Subtracting 776 from 790 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
The number 97 fits into 140 1 times, leaving a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 6637.381
Subtract 97 from 140 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
97 goes into 430 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 6637.3814
Deduct 388 from 430 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
97 goes into 420 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 6637.38144
If we take 388 away from 420, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 6637.38144 and a remainder of 3.2e-05.
