We're dividing 62172456 by 644 
We're looking to find how many times 644 goes into 62172456.

Going ahead to step 1:
When dividing 6 by 644, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 644

On to step 2:
The number 644 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 644

Going ahead to step 3:
644 can be fit into 621 0 times, resulting in a remainder of 621.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 621, we get 621.
Append the next digit (7) from the dividend to 621 and continue with: 6217 / 644

On to step 4:
6217 divided by 644 is 9 with a remainder of 421.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 5796 from 6217, we get 421.
Include the next digit (2) from the dividend after 421, then repeat: 4212 / 644

Advancing to step 5:
The number 644 fits into 4212 6 times, leaving a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 348 after subtracting 3864 from 4212.
Grab the next digit (4) from the dividend, add it to 348, then carry on: 3484 / 644

Advancing to step 6:
644 goes into 3484 5 times with a remainder of 264.
Use 5 as the next digit of our solution. 
Result so far: 965.0
Deduct 3220 from 3484 and we're left with 264.
Fetch the next digit (5) from the dividend, attach it to 264 and continue: 2645 / 644

Advancing to step 7:
2645 divided by 644 is 4 with a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 9654.0
Deduct 2576 from 2645 and we're left with 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 644

Step 8:
644 can be fit into 696 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 96541.0
Deduct 644 from 696 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
When dividing 520 by 644, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 96541.0
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
644 goes into 5200 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 96541.08
If we subtract 5152 from 5200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 644 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 96541.08
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
If we divide 4800 by 644, we get 7 and a remainder of 292.
Record the quotient 7 as the next digit in the result. 
Result so far: 96541.0807
Subtracting 4508 from 4800 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 13:
If we divide 2920 by 644, we get 4 and a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 96541.08074
Subtracting 2576 from 2920 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.

Moving on to step 14:
644 goes into 3440 5 times with a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 96541.080745
Deduct 3220 from 3440 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
644 can be fit into 2200 3 times, resulting in a remainder of 268.
The number 3 becomes the next digit in our result. 
Result so far: 96541.0807453
If we take 1932 away from 2200, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 16:
When dividing 2680 by 644, we get 4 with a remainder of 104.
The next digit of our result is 4. 
Result so far: 96541.08074534
If we take 2576 away from 2680, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 96541.08074534 with a remainder of 1.04e-07.
