Let's divide 64864292 by 643
Let's see how many times 643 fits into 64864292.

Advancing to step 1:
The number 643 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 643

Going ahead to step 2:
When dividing 64 by 643, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 643

Let's proceed to step 3:
When dividing 648 by 643, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 643 from 648 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 643

Advancing to step 4:
643 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 56 and we're left with 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 643

Going ahead to step 5:
564 divided by 643 is 0 with a remainder of 564.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 564, we get 564.
Fetch the next digit (2) from the dividend, attach it to 564 and continue: 5642 / 643

Step 6:
643 can be fit into 5642 8 times, resulting in a remainder of 498.
Write down 8 as next digit of the result. 
Result so far: 1008.0
Subtract 5144 from 5642 to get 498.
Fetch the next digit (9) from the dividend, attach it to 498 and continue: 4989 / 643

Advancing to step 7:
643 goes into 4989 7 times with a remainder of 488.
The number 7 becomes the next digit in our result. 
Result so far: 10087.0
If we take 4501 away from 4989, we end up with 488.
Grab the next digit (2) from the dividend, add it to 488, then carry on: 4882 / 643

Going ahead to step 8:
The number 643 fits into 4882 7 times, leaving a remainder of 381.
The number 7 becomes the next digit in our result. 
Result so far: 100877.0
The remainder is 381 after subtracting 4501 from 4882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 9:
The number 643 fits into 3810 5 times, leaving a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 100877.5
If we subtract 3215 from 3810, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Moving on to step 10:
If we divide 5950 by 643, we get 9 and a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 100877.59
If we take 5787 away from 5950, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 11:
643 goes into 1630 2 times with a remainder of 344.
The next digit of our result is 2. 
Result so far: 100877.592
Subtracting 1286 from 1630 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 12:
If we divide 3440 by 643, we get 5 and a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 100877.5925
Deduct 3215 from 3440 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 13:
When dividing 2250 by 643, we get 3 with a remainder of 321.
Write down 3 as next digit of the result. 
Result so far: 100877.59253
Deduct 1929 from 2250 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 14:
643 can be fit into 3210 4 times, resulting in a remainder of 638.
Put 4 as the next digit of the answer. 
Result so far: 100877.592534
If we take 2572 away from 3210, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 15:
643 goes into 6380 9 times with a remainder of 593.
The number 9 becomes the next digit in our result. 
Result so far: 100877.5925349
Deduct 5787 from 6380 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Moving on to step 16:
643 goes into 5930 9 times with a remainder of 143.
Record the quotient 9 as the next digit in the result. 
Result so far: 100877.59253499
Deduct 5787 from 5930 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

In conclusion, the division gives 100877.59253499 with a balance of 1.43e-07.
