64319689 ÷ 43 
Let's see how many times 43 fits into 64319689.

On to step 1:
When dividing 6 by 43, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 43

Advancing to step 2:
43 goes into 64 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 43 from 64 to get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 43

Step 3:
When dividing 213 by 43, we get 4 with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 172 from 213 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 43

Going ahead to step 4:
The number 43 fits into 411 9 times, leaving a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 387 from 411 to get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 43

Going ahead to step 5:
249 divided by 43 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 1495.0
Deduct 215 from 249 and we're left with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 43

On to step 6:
The number 43 fits into 346 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 14958.0
Subtract 344 from 346 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 43

Going ahead to step 7:
43 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 149580.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 43

Moving on to step 8:
289 divided by 43 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 1495806.0
Subtracting 258 from 289 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
If we divide 310 by 43, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1495806.7
Subtract 301 from 310 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 43 fits into 90 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1495806.72
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 43 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1495806.72
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
43 can be fit into 400 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 1495806.7209
Subtracting 387 from 400 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
43 goes into 130 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1495806.72093
Deduct 129 from 130 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
10 divided by 43 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1495806.72093
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
100 divided by 43 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1495806.7209302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 16:
When dividing 140 by 43, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1495806.72093023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 1495806.72093023 and a remainder of 1.1e-08.
