We look at the division of 47742637 by 644 
Our goal is to divide 47742637 by 644.

On to step 1:
If we divide 4 by 644, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 644

On to step 2:
If we divide 47 by 644, we get 0 and a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 644

Advancing to step 3:
644 can be fit into 477 0 times, resulting in a remainder of 477.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 477 and we're left with 477.
Include the next digit (4) from the dividend after 477, then repeat: 4774 / 644

Going ahead to step 4:
The number 644 fits into 4774 7 times, leaving a remainder of 266.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4508 from 4774 leaves us with 266.
Append the next digit (2) from the dividend to 266 and continue with: 2662 / 644

Let's proceed to step 5:
If we divide 2662 by 644, we get 4 and a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 2576 away from 2662, we end up with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 644

Advancing to step 6:
When dividing 866 by 644, we get 1 with a remainder of 222.
Use 1 as the next digit of our solution. 
Result so far: 741.0
Deduct 644 from 866 and we're left with 222.
Grab the next digit (3) from the dividend, add it to 222, then carry on: 2223 / 644

On to step 7:
When dividing 2223 by 644, we get 3 with a remainder of 291.
Record the quotient 3 as the next digit in the result. 
Result so far: 7413.0
Subtract 1932 from 2223 to get 291.
Bring next digit (7) of the dividend behind the 291 and repeat the process: 2917 / 644

Advancing to step 8:
2917 divided by 644 is 4 with a remainder of 341.
Record the quotient 4 as the next digit in the result. 
Result so far: 74134.0
If we subtract 2576 from 2917, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
3410 divided by 644 is 5 with a remainder of 190.
The next digit of our result is 5. 
Result so far: 74134.5
The remainder is 190 after subtracting 3220 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
644 goes into 1900 2 times with a remainder of 612.
Use 2 as the next digit of our solution. 
Result so far: 74134.52
If we take 1288 away from 1900, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 11:
644 goes into 6120 9 times with a remainder of 324.
The next digit of our result is 9. 
Result so far: 74134.529
Deduct 5796 from 6120 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 12:
3240 divided by 644 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 74134.5295
Subtracting 3220 from 3240 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 644 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 74134.5295
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
2000 divided by 644 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 74134.529503
Deduct 1932 from 2000 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
When dividing 680 by 644, we get 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 74134.5295031
Subtract 644 from 680 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 16:
360 divided by 644 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 74134.5295031
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 74134.5295031 with a balance of 3.6e-07.
