We look at the division of 23208649 by 643 
We want to divide 23208649 by 643.

Moving on to step 1:
643 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 643

Moving on to step 2:
23 divided by 643 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 643

Advancing to step 3:
When dividing 232 by 643, we get 0 with a remainder of 232.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 232 and we're left with 232.
Append the next digit (0) from the dividend to 232 and continue with: 2320 / 643

Moving on to step 4:
The number 643 fits into 2320 3 times, leaving a remainder of 391.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1929 from 2320 and we're left with 391.
Grab the next digit (8) from the dividend, add it to 391, then carry on: 3918 / 643

Let's proceed to step 5:
If we divide 3918 by 643, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 3858 away from 3918, we end up with 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 643

Advancing to step 6:
The number 643 fits into 606 0 times, leaving a remainder of 606.
The next digit of our result is 0. 
Result so far: 360.0
If we subtract 0 from 606, we get 606.
Fetch the next digit (4) from the dividend, attach it to 606 and continue: 6064 / 643

Moving on to step 7:
If we divide 6064 by 643, we get 9 and a remainder of 277.
Use 9 as the next digit of our solution. 
Result so far: 3609.0
If we subtract 5787 from 6064, we get 277.
Grab the next digit (9) from the dividend, add it to 277, then carry on: 2779 / 643

On to step 8:
643 can be fit into 2779 4 times, resulting in a remainder of 207.
Record the quotient 4 as the next digit in the result. 
Result so far: 36094.0
If we subtract 2572 from 2779, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 9:
643 can be fit into 2070 3 times, resulting in a remainder of 141.
The next digit of our result is 3. 
Result so far: 36094.3
Deduct 1929 from 2070 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 10:
643 goes into 1410 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 36094.32
If we subtract 1286 from 1410, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
643 goes into 1240 1 times with a remainder of 597.
Record the quotient 1 as the next digit in the result. 
Result so far: 36094.321
If we take 643 away from 1240, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Step 12:
5970 divided by 643 is 9 with a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 36094.3219
Deduct 5787 from 5970 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 13:
The number 643 fits into 1830 2 times, leaving a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 36094.32192
The remainder is 544 after subtracting 1286 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 14:
If we divide 5440 by 643, we get 8 and a remainder of 296.
The next digit of our result is 8. 
Result so far: 36094.321928
The remainder is 296 after subtracting 5144 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
When dividing 2960 by 643, we get 4 with a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 36094.3219284
Subtract 2572 from 2960 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 16:
When dividing 3880 by 643, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 36094.32192846
Subtract 3858 from 3880 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 36094.32192846 with a remaining 2.2e-08.
