We're dividing 47879581 by 644 
Let's see how many times 644 fits into 47879581.

On to step 1:
4 divided by 644 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 644

On to step 2:
When dividing 47 by 644, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 644

Let's proceed to step 3:
If we divide 478 by 644, we get 0 and a remainder of 478.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 478 and we're left with 478.
Fetch the next digit (7) from the dividend, attach it to 478 and continue: 4787 / 644

On to step 4:
644 goes into 4787 7 times with a remainder of 279.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 4508 away from 4787, we end up with 279.
Grab the next digit (9) from the dividend, add it to 279, then carry on: 2799 / 644

Going ahead to step 5:
The number 644 fits into 2799 4 times, leaving a remainder of 223.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we take 2576 away from 2799, we end up with 223.
Grab the next digit (5) from the dividend, add it to 223, then carry on: 2235 / 644

On to step 6:
If we divide 2235 by 644, we get 3 and a remainder of 303.
Write down 3 as next digit of the result. 
Result so far: 743.0
Deduct 1932 from 2235 and we're left with 303.
Take the next digit (8) from the dividend and append it to 303, then repeat: 3038 / 644

Advancing to step 7:
3038 divided by 644 is 4 with a remainder of 462.
Write down 4 as next digit of the result. 
Result so far: 7434.0
If we subtract 2576 from 3038, we get 462.
Include the next digit (1) from the dividend after 462, then repeat: 4621 / 644

On to step 8:
If we divide 4621 by 644, we get 7 and a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 74347.0
Subtract 4508 from 4621 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
The number 644 fits into 1130 1 times, leaving a remainder of 486.
Put 1 as the next digit of the answer. 
Result so far: 74347.1
Subtracting 644 from 1130 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 10:
4860 divided by 644 is 7 with a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 74347.17
Subtract 4508 from 4860 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 11:
The number 644 fits into 3520 5 times, leaving a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 74347.175
Deduct 3220 from 3520 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 12:
The number 644 fits into 3000 4 times, leaving a remainder of 424.
Put 4 as the next digit of the answer. 
Result so far: 74347.1754
Subtracting 2576 from 3000 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 13:
644 goes into 4240 6 times with a remainder of 376.
The next digit of our result is 6. 
Result so far: 74347.17546
If we take 3864 away from 4240, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
If we divide 3760 by 644, we get 5 and a remainder of 540.
The next digit of our result is 5. 
Result so far: 74347.175465
Subtract 3220 from 3760 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
The number 644 fits into 5400 8 times, leaving a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 74347.1754658
Deduct 5152 from 5400 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 16:
644 can be fit into 2480 3 times, resulting in a remainder of 548.
Use 3 as the next digit of our solution. 
Result so far: 74347.17546583
If we subtract 1932 from 2480, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

In conclusion, the division gives 74347.17546583 with a balance of 5.48e-07.
