We're dividing 9962560 by 641 
We want to divide 9962560 by 641.

Step 1:
If we divide 9 by 641, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 641

Let's proceed to step 2:
641 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 641

On to step 3:
641 goes into 996 1 times with a remainder of 355.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 641 away from 996, we end up with 355.
Fetch the next digit (2) from the dividend, attach it to 355 and continue: 3552 / 641

Moving on to step 4:
When dividing 3552 by 641, we get 5 with a remainder of 347.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 3205 away from 3552, we end up with 347.
Append the next digit (5) from the dividend to 347 and continue with: 3475 / 641

Advancing to step 5:
When dividing 3475 by 641, we get 5 with a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 155.0
The remainder is 270 after subtracting 3205 from 3475.
Take the next digit (6) from the dividend and append it to 270, then repeat: 2706 / 641

Let's proceed to step 6:
641 goes into 2706 4 times with a remainder of 142.
The next digit of our result is 4. 
Result so far: 1554.0
If we take 2564 away from 2706, we end up with 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 641

Step 7:
641 goes into 1420 2 times with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 15542.0
The remainder is 138 after subtracting 1282 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 8:
If we divide 1380 by 641, we get 2 and a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 15542.2
If we subtract 1282 from 1380, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
641 can be fit into 980 1 times, resulting in a remainder of 339.
The number 1 becomes the next digit in our result. 
Result so far: 15542.21
Subtract 641 from 980 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 10:
The number 641 fits into 3390 5 times, leaving a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 15542.215
Deduct 3205 from 3390 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 11:
When dividing 1850 by 641, we get 2 with a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 15542.2152
Subtracting 1282 from 1850 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
641 can be fit into 5680 8 times, resulting in a remainder of 552.
Put 8 as the next digit of the answer. 
Result so far: 15542.21528
Subtracting 5128 from 5680 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 13:
When dividing 5520 by 641, we get 8 with a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 15542.215288
If we take 5128 away from 5520, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final result is 15542.215288 with a remainder of 3.92e-05.
