We're dividing 96018600 by 644 
We want to divide 96018600 by 644.

Moving on to step 1:
If we divide 9 by 644, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 644

Advancing to step 2:
96 divided by 644 is 0 with a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 644

Going ahead to step 3:
When dividing 960 by 644, we get 1 with a remainder of 316.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 644 from 960 and we're left with 316.
Take the next digit (1) from the dividend and append it to 316, then repeat: 3161 / 644

Going ahead to step 4:
644 can be fit into 3161 4 times, resulting in a remainder of 585.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 585 after subtracting 2576 from 3161.
Take the next digit (8) from the dividend and append it to 585, then repeat: 5858 / 644

Step 5:
644 can be fit into 5858 9 times, resulting in a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 149.0
If we subtract 5796 from 5858, we get 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 644

On to step 6:
644 can be fit into 626 0 times, resulting in a remainder of 626.
The number 0 becomes the next digit in our result. 
Result so far: 1490.0
Deduct 0 from 626 and we're left with 626.
Append the next digit (0) from the dividend to 626 and continue with: 6260 / 644

Step 7:
644 can be fit into 6260 9 times, resulting in a remainder of 464.
Use 9 as the next digit of our solution. 
Result so far: 14909.0
Subtract 5796 from 6260 to get 464.
Grab the next digit (0) from the dividend, add it to 464, then carry on: 4640 / 644

Moving on to step 8:
644 goes into 4640 7 times with a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 149097.0
Deduct 4508 from 4640 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 9:
When dividing 1320 by 644, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 149097.2
Deduct 1288 from 1320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
When dividing 320 by 644, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 149097.2
Subtract 0 from 320 to 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.

On to step 11:
The number 644 fits into 3200 4 times, leaving a remainder of 624.
The next digit of our result is 4. 
Result so far: 149097.204
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.

Step 12:
644 goes into 6240 9 times with a remainder of 444.
Write down 9 as next digit of the result. 
Result so far: 149097.2049
Subtracting 5796 from 6240 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 13:
The number 644 fits into 4440 6 times, leaving a remainder of 576.
Use 6 as the next digit of our solution. 
Result so far: 149097.20496
The remainder is 576 after subtracting 3864 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 14:
The number 644 fits into 5760 8 times, leaving a remainder of 608.
Put 8 as the next digit of the answer. 
Result so far: 149097.204968
Subtract 5152 from 5760 to 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.

Moving on to step 15:
When dividing 6080 by 644, we get 9 with a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 149097.2049689
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.

Step 16:
2840 divided by 644 is 4 with a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 149097.20496894
Subtract 2576 from 2840 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

The quotient of the division is 149097.20496894, and the remainder is 2.64e-07.
