We divide 19798924 by 643
We want to divide 19798924 by 643.

Let's proceed to step 1:
If we divide 1 by 643, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 643

Moving on to step 2:
If we divide 19 by 643, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 643

Moving on to step 3:
197 divided by 643 is 0 with a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Grab the next digit (9) from the dividend, add it to 197, then carry on: 1979 / 643

Going ahead to step 4:
643 can be fit into 1979 3 times, resulting in a remainder of 50.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 50 after subtracting 1929 from 1979.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 643

Moving on to step 5:
When dividing 508 by 643, we get 0 with a remainder of 508.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 508 to get 508.
Take the next digit (9) from the dividend and append it to 508, then repeat: 5089 / 643

Moving on to step 6:
5089 divided by 643 is 7 with a remainder of 588.
Write down 7 as next digit of the result. 
Result so far: 307.0
Subtract 4501 from 5089 to get 588.
Bring next digit (2) of the dividend behind the 588 and repeat the process: 5882 / 643

Moving on to step 7:
643 goes into 5882 9 times with a remainder of 95.
The next digit of our result is 9. 
Result so far: 3079.0
Subtract 5787 from 5882 to get 95.
Take the next digit (4) from the dividend and append it to 95, then repeat: 954 / 643

Advancing to step 8:
954 divided by 643 is 1 with a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 30791.0
Deduct 643 from 954 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
643 goes into 3110 4 times with a remainder of 538.
Record the quotient 4 as the next digit in the result. 
Result so far: 30791.4
Deduct 2572 from 3110 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Moving on to step 10:
When dividing 5380 by 643, we get 8 with a remainder of 236.
The next digit of our result is 8. 
Result so far: 30791.48
Subtract 5144 from 5380 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 11:
When dividing 2360 by 643, we get 3 with a remainder of 431.
Put 3 as the next digit of the answer. 
Result so far: 30791.483
Subtract 1929 from 2360 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 12:
4310 divided by 643 is 6 with a remainder of 452.
The next digit of our result is 6. 
Result so far: 30791.4836
If we subtract 3858 from 4310, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 13:
643 goes into 4520 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 30791.48367
If we subtract 4501 from 4520, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
190 divided by 643 is 0 with a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 30791.48367
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
When dividing 1900 by 643, we get 2 with a remainder of 614.
The next digit of our result is 2. 
Result so far: 30791.4836702
If we subtract 1286 from 1900, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 16:
643 can be fit into 6140 9 times, resulting in a remainder of 353.
The number 9 becomes the next digit in our result. 
Result so far: 30791.48367029
Subtract 5787 from 6140 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Our division results in 30791.48367029 with a remaining 3.53e-07.
