65137358 ÷ 644 
Let's see how many times 644 fits into 65137358.

Let's proceed to step 1:
644 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 644

Step 2:
When dividing 65 by 644, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 644

Going ahead to step 3:
When dividing 651 by 644, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 644 from 651, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 644

On to step 4:
644 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 644

Moving on to step 5:
If we divide 737 by 644, we get 1 and a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
If we subtract 644 from 737, we get 93.
Append the next digit (3) from the dividend to 93 and continue with: 933 / 644

On to step 6:
If we divide 933 by 644, we get 1 and a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
If we take 644 away from 933, we end up with 289.
Include the next digit (5) from the dividend after 289, then repeat: 2895 / 644

On to step 7:
644 can be fit into 2895 4 times, resulting in a remainder of 319.
Record the quotient 4 as the next digit in the result. 
Result so far: 10114.0
Deduct 2576 from 2895 and we're left with 319.
Bring next digit (8) of the dividend behind the 319 and repeat the process: 3198 / 644

Step 8:
644 can be fit into 3198 4 times, resulting in a remainder of 622.
Use 4 as the next digit of our solution. 
Result so far: 101144.0
If we take 2576 away from 3198, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 9:
When dividing 6220 by 644, we get 9 with a remainder of 424.
The number 9 becomes the next digit in our result. 
Result so far: 101144.9
If we take 5796 away from 6220, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 10:
When dividing 4240 by 644, we get 6 with a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 101144.96
The remainder is 376 after subtracting 3864 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 11:
644 goes into 3760 5 times with a remainder of 540.
The next digit of our result is 5. 
Result so far: 101144.965
If we subtract 3220 from 3760, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 12:
If we divide 5400 by 644, we get 8 and a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 101144.9658
Subtracting 5152 from 5400 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 13:
When dividing 2480 by 644, we get 3 with a remainder of 548.
Write down 3 as next digit of the result. 
Result so far: 101144.96583
If we subtract 1932 from 2480, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 14:
When dividing 5480 by 644, we get 8 with a remainder of 328.
Use 8 as the next digit of our solution. 
Result so far: 101144.965838
Subtracting 5152 from 5480 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 15:
If we divide 3280 by 644, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 101144.9658385
Subtracting 3220 from 3280 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
If we divide 600 by 644, we get 0 and a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 101144.9658385
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 101144.9658385, and the remainder is 6e-07.
