We divide 75706384 by 644
We want to divide 75706384 by 644.

Advancing to step 1:
The number 644 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 644

On to step 2:
644 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 644

Going ahead to step 3:
The number 644 fits into 757 1 times, leaving a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 644 from 757, we get 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 644

On to step 4:
644 can be fit into 1130 1 times, resulting in a remainder of 486.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 644 away from 1130, we end up with 486.
Fetch the next digit (6) from the dividend, attach it to 486 and continue: 4866 / 644

Going ahead to step 5:
If we divide 4866 by 644, we get 7 and a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 117.0
If we take 4508 away from 4866, we end up with 358.
Fetch the next digit (3) from the dividend, attach it to 358 and continue: 3583 / 644

On to step 6:
644 can be fit into 3583 5 times, resulting in a remainder of 363.
Use 5 as the next digit of our solution. 
Result so far: 1175.0
Subtracting 3220 from 3583 leaves us with 363.
Append the next digit (8) from the dividend to 363 and continue with: 3638 / 644

Let's proceed to step 7:
When dividing 3638 by 644, we get 5 with a remainder of 418.
Use 5 as the next digit of our solution. 
Result so far: 11755.0
If we subtract 3220 from 3638, we get 418.
Append the next digit (4) from the dividend to 418 and continue with: 4184 / 644

On to step 8:
If we divide 4184 by 644, we get 6 and a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 117556.0
If we subtract 3864 from 4184, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 9:
644 goes into 3200 4 times with a remainder of 624.
The number 4 becomes the next digit in our result. 
Result so far: 117556.4
Deduct 2576 from 3200 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 10:
644 goes into 6240 9 times with a remainder of 444.
The number 9 becomes the next digit in our result. 
Result so far: 117556.49
The remainder is 444 after subtracting 5796 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 11:
644 goes into 4440 6 times with a remainder of 576.
Write down 6 as next digit of the result. 
Result so far: 117556.496
Subtracting 3864 from 4440 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 12:
5760 divided by 644 is 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 117556.4968
If we subtract 5152 from 5760, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
6080 divided by 644 is 9 with a remainder of 284.
Put 9 as the next digit of the answer. 
Result so far: 117556.49689
The remainder is 284 after subtracting 5796 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 14:
644 can be fit into 2840 4 times, resulting in a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 117556.496894
The remainder is 264 after subtracting 2576 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 15:
When dividing 2640 by 644, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 117556.4968944
Deduct 2576 from 2640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 117556.4968944 with a remainder of 6.4e-07.
