We're dividing 43175213 by 644 
We want to divide 43175213 by 644.

Going ahead to step 1:
4 divided by 644 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 644

On to step 2:
644 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 644

Step 3:
644 goes into 431 0 times with a remainder of 431.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 431 leaves us with 431.
Append the next digit (7) from the dividend to 431 and continue with: 4317 / 644

Advancing to step 4:
The number 644 fits into 4317 6 times, leaving a remainder of 453.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 3864 from 4317 to get 453.
Grab the next digit (5) from the dividend, add it to 453, then carry on: 4535 / 644

Moving on to step 5:
If we divide 4535 by 644, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtracting 4508 from 4535 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 644

Advancing to step 6:
If we divide 272 by 644, we get 0 and a remainder of 272.
Write down 0 as next digit of the result. 
Result so far: 670.0
The remainder is 272 after subtracting 0 from 272.
Take the next digit (1) from the dividend and append it to 272, then repeat: 2721 / 644

On to step 7:
2721 divided by 644 is 4 with a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 6704.0
Deduct 2576 from 2721 and we're left with 145.
Append the next digit (3) from the dividend to 145 and continue with: 1453 / 644

Let's proceed to step 8:
1453 divided by 644 is 2 with a remainder of 165.
The next digit of our result is 2. 
Result so far: 67042.0
If we subtract 1288 from 1453, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
When dividing 1650 by 644, we get 2 with a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 67042.2
Deduct 1288 from 1650 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.

On to step 10:
The number 644 fits into 3620 5 times, leaving a remainder of 400.
The next digit of our result is 5. 
Result so far: 67042.25
If we subtract 3220 from 3620, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
If we divide 4000 by 644, we get 6 and a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 67042.256
Deduct 3864 from 4000 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
If we divide 1360 by 644, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 67042.2562
The remainder is 72 after subtracting 1288 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
644 can be fit into 720 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 67042.25621
If we subtract 644 from 720, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 14:
644 goes into 760 1 times with a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 67042.256211
Subtract 644 from 760 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 67042.256211 with a remaining 1.16e-05.
