56936445 ÷ 643 
Our goal is to divide 56936445 by 643.

Let's proceed to step 1:
5 divided by 643 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 643

Let's proceed to step 2:
643 can be fit into 56 0 times, resulting in a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 643

Step 3:
If we divide 569 by 643, we get 0 and a remainder of 569.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 569 to get 569.
Include the next digit (3) from the dividend after 569, then repeat: 5693 / 643

Step 4:
When dividing 5693 by 643, we get 8 with a remainder of 549.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5144 from 5693 leaves us with 549.
Grab the next digit (6) from the dividend, add it to 549, then carry on: 5496 / 643

Moving on to step 5:
643 can be fit into 5496 8 times, resulting in a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 5144 from 5496, we get 352.
Grab the next digit (4) from the dividend, add it to 352, then carry on: 3524 / 643

On to step 6:
3524 divided by 643 is 5 with a remainder of 309.
Write down 5 as next digit of the result. 
Result so far: 885.0
Deduct 3215 from 3524 and we're left with 309.
Include the next digit (4) from the dividend after 309, then repeat: 3094 / 643

Advancing to step 7:
643 can be fit into 3094 4 times, resulting in a remainder of 522.
Record the quotient 4 as the next digit in the result. 
Result so far: 8854.0
Subtracting 2572 from 3094 leaves us with 522.
Include the next digit (5) from the dividend after 522, then repeat: 5225 / 643

Moving on to step 8:
643 can be fit into 5225 8 times, resulting in a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 88548.0
Deduct 5144 from 5225 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
If we divide 810 by 643, we get 1 and a remainder of 167.
Use 1 as the next digit of our solution. 
Result so far: 88548.1
Subtract 643 from 810 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 10:
The number 643 fits into 1670 2 times, leaving a remainder of 384.
The next digit of our result is 2. 
Result so far: 88548.12
Deduct 1286 from 1670 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 11:
643 goes into 3840 5 times with a remainder of 625.
The next digit of our result is 5. 
Result so far: 88548.125
If we take 3215 away from 3840, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 12:
643 can be fit into 6250 9 times, resulting in a remainder of 463.
The next digit of our result is 9. 
Result so far: 88548.1259
If we take 5787 away from 6250, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 13:
The number 643 fits into 4630 7 times, leaving a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 88548.12597
Subtract 4501 from 4630 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 14:
The number 643 fits into 1290 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 88548.125972
The remainder is 4 after subtracting 1286 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
643 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 88548.125972
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
When dividing 400 by 643, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 88548.125972
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 88548.125972 and a remainder of 4e-07.
