We divide 643583 by 97
We want to divide 643583 by 97.

Going ahead to step 1:
97 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 97

On to step 2:
64 divided by 97 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 97

Advancing to step 3:
The number 97 fits into 643 6 times, leaving a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 582 from 643 and we're left with 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 97

Moving on to step 4:
97 can be fit into 615 6 times, resulting in a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 582 from 615 to get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 97

Advancing to step 5:
The number 97 fits into 338 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
The remainder is 47 after subtracting 291 from 338.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 97

Advancing to step 6:
473 divided by 97 is 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 6634.0
If we take 388 away from 473, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 7:
97 can be fit into 850 8 times, resulting in a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 6634.8
The remainder is 74 after subtracting 776 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
97 goes into 740 7 times with a remainder of 61.
Use 7 as the next digit of our solution. 
Result so far: 6634.87
If we subtract 679 from 740, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
97 goes into 610 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6634.876
Subtract 582 from 610 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
When dividing 280 by 97, we get 2 with a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 6634.8762
Subtracting 194 from 280 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 11:
If we divide 860 by 97, we get 8 and a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 6634.87628
If we take 776 away from 860, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
840 divided by 97 is 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 6634.876288
Subtract 776 from 840 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 6634.876288, and the remainder is 6.4e-06.
