Let's divide 5743670 by 644
Our goal is to divide 5743670 by 644.

Advancing to step 1:
644 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 644

Advancing to step 2:
57 divided by 644 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 644

Step 3:
When dividing 574 by 644, we get 0 with a remainder of 574.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 574 leaves us with 574.
Append the next digit (3) from the dividend to 574 and continue with: 5743 / 644

Let's proceed to step 4:
The number 644 fits into 5743 8 times, leaving a remainder of 591.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5152 away from 5743, we end up with 591.
Grab the next digit (6) from the dividend, add it to 591, then carry on: 5916 / 644

Let's proceed to step 5:
5916 divided by 644 is 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 5796 from 5916, we get 120.
Append the next digit (7) from the dividend to 120 and continue with: 1207 / 644

Moving on to step 6:
644 goes into 1207 1 times with a remainder of 563.
The next digit of our result is 1. 
Result so far: 891.0
If we subtract 644 from 1207, we get 563.
Fetch the next digit (0) from the dividend, attach it to 563 and continue: 5630 / 644

Advancing to step 7:
5630 divided by 644 is 8 with a remainder of 478.
Use 8 as the next digit of our solution. 
Result so far: 8918.0
The remainder is 478 after subtracting 5152 from 5630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 8:
644 can be fit into 4780 7 times, resulting in a remainder of 272.
Use 7 as the next digit of our solution. 
Result so far: 8918.7
Subtract 4508 from 4780 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 9:
If we divide 2720 by 644, we get 4 and a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 8918.74
Subtracting 2576 from 2720 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
When dividing 1440 by 644, we get 2 with a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 8918.742
If we subtract 1288 from 1440, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
644 goes into 1520 2 times with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 8918.7422
Subtract 1288 from 1520 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 8918.7422 with a remaining 0.00232.
