Let's divide 82418896 by 643
We want to figure out the number of times 82418896 can be divided by 643.

Going ahead to step 1:
When dividing 8 by 643, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 643

Advancing to step 2:
If we divide 82 by 643, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Append the next digit (4) from the dividend to 82 and continue with: 824 / 643

Going ahead to step 3:
If we divide 824 by 643, we get 1 and a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 643 away from 824, we end up with 181.
Take the next digit (1) from the dividend and append it to 181, then repeat: 1811 / 643

Step 4:
643 can be fit into 1811 2 times, resulting in a remainder of 525.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1286 from 1811 to get 525.
Include the next digit (8) from the dividend after 525, then repeat: 5258 / 643

Moving on to step 5:
5258 divided by 643 is 8 with a remainder of 114.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 5144 from 5258, we get 114.
Append the next digit (8) from the dividend to 114 and continue with: 1148 / 643

Let's proceed to step 6:
643 can be fit into 1148 1 times, resulting in a remainder of 505.
Put 1 as the next digit of the answer. 
Result so far: 1281.0
Subtracting 643 from 1148 leaves us with 505.
Take the next digit (9) from the dividend and append it to 505, then repeat: 5059 / 643

Moving on to step 7:
643 goes into 5059 7 times with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 12817.0
Subtracting 4501 from 5059 leaves us with 558.
Append the next digit (6) from the dividend to 558 and continue with: 5586 / 643

Advancing to step 8:
If we divide 5586 by 643, we get 8 and a remainder of 442.
Record the quotient 8 as the next digit in the result. 
Result so far: 128178.0
Deduct 5144 from 5586 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 9:
4420 divided by 643 is 6 with a remainder of 562.
The next digit of our result is 6. 
Result so far: 128178.6
Subtracting 3858 from 4420 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 10:
The number 643 fits into 5620 8 times, leaving a remainder of 476.
Use 8 as the next digit of our solution. 
Result so far: 128178.68
The remainder is 476 after subtracting 5144 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 11:
If we divide 4760 by 643, we get 7 and a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 128178.687
If we subtract 4501 from 4760, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 12:
643 can be fit into 2590 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 128178.6874
If we subtract 2572 from 2590, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
643 goes into 180 0 times with a remainder of 180.
The next digit of our result is 0. 
Result so far: 128178.6874
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
643 can be fit into 1800 2 times, resulting in a remainder of 514.
Use 2 as the next digit of our solution. 
Result so far: 128178.687402
Subtracting 1286 from 1800 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 15:
If we divide 5140 by 643, we get 7 and a remainder of 639.
Write down 7 as next digit of the result. 
Result so far: 128178.6874027
Subtracting 4501 from 5140 leaves us with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Let's proceed to step 16:
643 can be fit into 6390 9 times, resulting in a remainder of 603.
Write down 9 as next digit of the result. 
Result so far: 128178.68740279
Subtracting 5787 from 6390 leaves us with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

After the division, we end up with 128178.68740279 and a remainder of 6.03e-07.
