We look at the division of 16130532 by 643 
Let's see how many times 643 fits into 16130532.

Advancing to step 1:
1 divided by 643 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 643

Moving on to step 2:
When dividing 16 by 643, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 643

Moving on to step 3:
643 can be fit into 161 0 times, resulting in a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 161, we get 161.
Grab the next digit (3) from the dividend, add it to 161, then carry on: 1613 / 643

Going ahead to step 4:
If we divide 1613 by 643, we get 2 and a remainder of 327.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1286 from 1613 leaves us with 327.
Bring next digit (0) of the dividend behind the 327 and repeat the process: 3270 / 643

Advancing to step 5:
The number 643 fits into 3270 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 3215 from 3270 leaves us with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 643

Let's proceed to step 6:
555 divided by 643 is 0 with a remainder of 555.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtracting 0 from 555 leaves us with 555.
Include the next digit (3) from the dividend after 555, then repeat: 5553 / 643

Let's proceed to step 7:
The number 643 fits into 5553 8 times, leaving a remainder of 409.
Put 8 as the next digit of the answer. 
Result so far: 2508.0
Subtract 5144 from 5553 to get 409.
Take the next digit (2) from the dividend and append it to 409, then repeat: 4092 / 643

Advancing to step 8:
If we divide 4092 by 643, we get 6 and a remainder of 234.
The number 6 becomes the next digit in our result. 
Result so far: 25086.0
Subtracting 3858 from 4092 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
643 goes into 2340 3 times with a remainder of 411.
Write down 3 as next digit of the result. 
Result so far: 25086.3
If we take 1929 away from 2340, we end up with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

On to step 10:
The number 643 fits into 4110 6 times, leaving a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 25086.36
If we subtract 3858 from 4110, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
643 goes into 2520 3 times with a remainder of 591.
The number 3 becomes the next digit in our result. 
Result so far: 25086.363
If we subtract 1929 from 2520, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 12:
643 can be fit into 5910 9 times, resulting in a remainder of 123.
Put 9 as the next digit of the answer. 
Result so far: 25086.3639
Subtracting 5787 from 5910 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 13:
643 can be fit into 1230 1 times, resulting in a remainder of 587.
The number 1 becomes the next digit in our result. 
Result so far: 25086.36391
If we take 643 away from 1230, we end up with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 14:
If we divide 5870 by 643, we get 9 and a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 25086.363919
Subtract 5787 from 5870 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 15:
643 goes into 830 1 times with a remainder of 187.
Record the quotient 1 as the next digit in the result. 
Result so far: 25086.3639191
The remainder is 187 after subtracting 643 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 16:
The number 643 fits into 1870 2 times, leaving a remainder of 584.
The next digit of our result is 2. 
Result so far: 25086.36391912
The remainder is 584 after subtracting 1286 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Our division results in 25086.36391912 with a remaining 5.84e-07.
