6423896 ÷ 534 
We want to figure out the number of times 6423896 can be divided by 534.

Advancing to step 1:
The number 534 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 / 534

Step 2:
If we divide 64 by 534, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 534

On to step 3:
The number 534 fits into 642 1 times, leaving a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 534 from 642 leaves us with 108.
Grab the next digit (3) from the dividend, add it to 108, then carry on: 1083 / 534

Going ahead to step 4:
1083 divided by 534 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1068 from 1083 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 534

Step 5:
534 can be fit into 158 0 times, resulting in a remainder of 158.
The next digit of our result is 0. 
Result so far: 120.0
If we take 0 away from 158, we end up with 158.
Take the next digit (9) from the dividend and append it to 158, then repeat: 1589 / 534

On to step 6:
If we divide 1589 by 534, we get 2 and a remainder of 521.
Record the quotient 2 as the next digit in the result. 
Result so far: 1202.0
The remainder is 521 after subtracting 1068 from 1589.
Grab the next digit (6) from the dividend, add it to 521, then carry on: 5216 / 534

Going ahead to step 7:
534 can be fit into 5216 9 times, resulting in a remainder of 410.
Put 9 as the next digit of the answer. 
Result so far: 12029.0
Subtracting 4806 from 5216 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 8:
4100 divided by 534 is 7 with a remainder of 362.
Put 7 as the next digit of the answer. 
Result so far: 12029.7
Deduct 3738 from 4100 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 9:
534 goes into 3620 6 times with a remainder of 416.
The next digit of our result is 6. 
Result so far: 12029.76
If we take 3204 away from 3620, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 10:
When dividing 4160 by 534, we get 7 with a remainder of 422.
Put 7 as the next digit of the answer. 
Result so far: 12029.767
If we subtract 3738 from 4160, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 11:
534 goes into 4220 7 times with a remainder of 482.
The number 7 becomes the next digit in our result. 
Result so far: 12029.7677
Subtract 3738 from 4220 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The final outcome is 12029.7677, with a leftover of 0.00482.
