45482982 ÷ 643 
We want to figure out the number of times 45482982 can be divided by 643.

Going ahead to step 1:
4 divided by 643 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 643

Let's proceed to step 2:
45 divided by 643 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 643

Let's proceed to step 3:
454 divided by 643 is 0 with a remainder of 454.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 454 and we're left with 454.
Include the next digit (8) from the dividend after 454, then repeat: 4548 / 643

Let's proceed to step 4:
The number 643 fits into 4548 7 times, leaving a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 4501 from 4548 to get 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 643

Moving on to step 5:
When dividing 472 by 643, we get 0 with a remainder of 472.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 472, we get 472.
Grab the next digit (9) from the dividend, add it to 472, then carry on: 4729 / 643

Let's proceed to step 6:
If we divide 4729 by 643, we get 7 and a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 707.0
The remainder is 228 after subtracting 4501 from 4729.
Append the next digit (8) from the dividend to 228 and continue with: 2288 / 643

On to step 7:
The number 643 fits into 2288 3 times, leaving a remainder of 359.
Put 3 as the next digit of the answer. 
Result so far: 7073.0
If we subtract 1929 from 2288, we get 359.
Fetch the next digit (2) from the dividend, attach it to 359 and continue: 3592 / 643

Step 8:
643 goes into 3592 5 times with a remainder of 377.
Write down 5 as next digit of the result. 
Result so far: 70735.0
The remainder is 377 after subtracting 3215 from 3592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
643 can be fit into 3770 5 times, resulting in a remainder of 555.
Write down 5 as next digit of the result. 
Result so far: 70735.5
If we subtract 3215 from 3770, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 10:
643 can be fit into 5550 8 times, resulting in a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 70735.58
Deduct 5144 from 5550 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 11:
643 goes into 4060 6 times with a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 70735.586
If we take 3858 away from 4060, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 12:
The number 643 fits into 2020 3 times, leaving a remainder of 91.
The next digit of our result is 3. 
Result so far: 70735.5863
Subtract 1929 from 2020 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 13:
643 can be fit into 910 1 times, resulting in a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 70735.58631
Deduct 643 from 910 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 14:
2670 divided by 643 is 4 with a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 70735.586314
The remainder is 98 after subtracting 2572 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 15:
If we divide 980 by 643, we get 1 and a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 70735.5863141
If we take 643 away from 980, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 16:
The number 643 fits into 3370 5 times, leaving a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 70735.58631415
If we take 3215 away from 3370, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

In conclusion, the division gives 70735.58631415 with a balance of 1.55e-07.
