We divide 75707447 by 644
We want to divide 75707447 by 644.

Going ahead to step 1:
The number 644 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 644

Step 2:
If we divide 75 by 644, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 644

Step 3:
644 can be fit into 757 1 times, resulting in a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 644 from 757 leaves us with 113.
Fetch the next digit (0) from the dividend, attach it to 113 and continue: 1130 / 644

Moving on to step 4:
The number 644 fits into 1130 1 times, leaving a remainder of 486.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 644 away from 1130, we end up with 486.
Bring next digit (7) of the dividend behind the 486 and repeat the process: 4867 / 644

Going ahead to step 5:
644 can be fit into 4867 7 times, resulting in a remainder of 359.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we subtract 4508 from 4867, we get 359.
Take the next digit (4) from the dividend and append it to 359, then repeat: 3594 / 644

Advancing to step 6:
644 goes into 3594 5 times with a remainder of 374.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
If we subtract 3220 from 3594, we get 374.
Include the next digit (4) from the dividend after 374, then repeat: 3744 / 644

Advancing to step 7:
When dividing 3744 by 644, we get 5 with a remainder of 524.
Use 5 as the next digit of our solution. 
Result so far: 11755.0
The remainder is 524 after subtracting 3220 from 3744.
Bring next digit (7) of the dividend behind the 524 and repeat the process: 5247 / 644

Advancing to step 8:
5247 divided by 644 is 8 with a remainder of 95.
The next digit of our result is 8. 
Result so far: 117558.0
Deduct 5152 from 5247 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
The number 644 fits into 950 1 times, leaving a remainder of 306.
Put 1 as the next digit of the answer. 
Result so far: 117558.1
The remainder is 306 after subtracting 644 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 10:
The number 644 fits into 3060 4 times, leaving a remainder of 484.
Use 4 as the next digit of our solution. 
Result so far: 117558.14
Subtract 2576 from 3060 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
644 goes into 4840 7 times with a remainder of 332.
The number 7 becomes the next digit in our result. 
Result so far: 117558.147
If we subtract 4508 from 4840, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 12:
3320 divided by 644 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 117558.1475
Deduct 3220 from 3320 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
The number 644 fits into 1000 1 times, leaving a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 117558.14751
Subtracting 644 from 1000 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 14:
644 goes into 3560 5 times with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 117558.147515
Subtract 3220 from 3560 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
If we divide 3400 by 644, we get 5 and a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 117558.1475155
Subtract 3220 from 3400 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 117558.1475155 with a remainder of 1.8e-06.
