We look at the division of 64436329 by 921 
Our goal is to divide 64436329 by 921.

Going ahead to step 1:
921 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 921

Let's proceed to step 2:
921 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 921

Let's proceed to step 3:
644 divided by 921 is 0 with a remainder of 644.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 644 after subtracting 0 from 644.
Append the next digit (3) from the dividend to 644 and continue with: 6443 / 921

Advancing to step 4:
921 goes into 6443 6 times with a remainder of 917.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5526 from 6443 and we're left with 917.
Grab the next digit (6) from the dividend, add it to 917, then carry on: 9176 / 921

On to step 5:
921 can be fit into 9176 9 times, resulting in a remainder of 887.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 8289 away from 9176, we end up with 887.
Grab the next digit (3) from the dividend, add it to 887, then carry on: 8873 / 921

Moving on to step 6:
When dividing 8873 by 921, we get 9 with a remainder of 584.
Use 9 as the next digit of our solution. 
Result so far: 699.0
Deduct 8289 from 8873 and we're left with 584.
Take the next digit (2) from the dividend and append it to 584, then repeat: 5842 / 921

Going ahead to step 7:
921 goes into 5842 6 times with a remainder of 316.
Write down 6 as next digit of the result. 
Result so far: 6996.0
Subtracting 5526 from 5842 leaves us with 316.
Bring next digit (9) of the dividend behind the 316 and repeat the process: 3169 / 921

Moving on to step 8:
If we divide 3169 by 921, we get 3 and a remainder of 406.
The number 3 becomes the next digit in our result. 
Result so far: 69963.0
The remainder is 406 after subtracting 2763 from 3169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 9:
921 goes into 4060 4 times with a remainder of 376.
Use 4 as the next digit of our solution. 
Result so far: 69963.4
Subtract 3684 from 4060 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
When dividing 3760 by 921, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 69963.44
If we take 3684 away from 3760, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 69963.44 with a remainder of 0.076.
