Let's divide 97687060 by 644
We're looking to find how many times 644 goes into 97687060.

Advancing to step 1:
644 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 644

Step 2:
97 divided by 644 is 0 with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Take the next digit (6) from the dividend and append it to 97, then repeat: 976 / 644

Going ahead to step 3:
When dividing 976 by 644, we get 1 with a remainder of 332.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 644 away from 976, we end up with 332.
Fetch the next digit (8) from the dividend, attach it to 332 and continue: 3328 / 644

Step 4:
The number 644 fits into 3328 5 times, leaving a remainder of 108.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 3220 from 3328 leaves us with 108.
Fetch the next digit (7) from the dividend, attach it to 108 and continue: 1087 / 644

Step 5:
The number 644 fits into 1087 1 times, leaving a remainder of 443.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 443 after subtracting 644 from 1087.
Take the next digit (0) from the dividend and append it to 443, then repeat: 4430 / 644

On to step 6:
644 goes into 4430 6 times with a remainder of 566.
The next digit of our result is 6. 
Result so far: 1516.0
Subtracting 3864 from 4430 leaves us with 566.
Take the next digit (6) from the dividend and append it to 566, then repeat: 5666 / 644

Let's proceed to step 7:
644 can be fit into 5666 8 times, resulting in a remainder of 514.
The number 8 becomes the next digit in our result. 
Result so far: 15168.0
Deduct 5152 from 5666 and we're left with 514.
Take the next digit (0) from the dividend and append it to 514, then repeat: 5140 / 644

Step 8:
When dividing 5140 by 644, we get 7 with a remainder of 632.
Use 7 as the next digit of our solution. 
Result so far: 151687.0
Subtract 4508 from 5140 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 9:
When dividing 6320 by 644, we get 9 with a remainder of 524.
The number 9 becomes the next digit in our result. 
Result so far: 151687.9
Subtract 5796 from 6320 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 10:
5240 divided by 644 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 151687.98
If we subtract 5152 from 5240, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 11:
880 divided by 644 is 1 with a remainder of 236.
Put 1 as the next digit of the answer. 
Result so far: 151687.981
If we take 644 away from 880, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 12:
If we divide 2360 by 644, we get 3 and a remainder of 428.
Put 3 as the next digit of the answer. 
Result so far: 151687.9813
Subtract 1932 from 2360 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 13:
644 can be fit into 4280 6 times, resulting in a remainder of 416.
Write down 6 as next digit of the result. 
Result so far: 151687.98136
The remainder is 416 after subtracting 3864 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 14:
The number 644 fits into 4160 6 times, leaving a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 151687.981366
Subtracting 3864 from 4160 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

In conclusion, the division gives 151687.981366 with a balance of 2.96e-05.
