We divide 61395332 by 644
Our goal is to divide 61395332 by 644.

Going ahead to step 1:
When dividing 6 by 644, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 644

Advancing to step 2:
644 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 644

Moving on to step 3:
When dividing 613 by 644, we get 0 with a remainder of 613.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 613 leaves us with 613.
Grab the next digit (9) from the dividend, add it to 613, then carry on: 6139 / 644

On to step 4:
The number 644 fits into 6139 9 times, leaving a remainder of 343.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 343 after subtracting 5796 from 6139.
Fetch the next digit (5) from the dividend, attach it to 343 and continue: 3435 / 644

Advancing to step 5:
The number 644 fits into 3435 5 times, leaving a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 3220 from 3435 to get 215.
Grab the next digit (3) from the dividend, add it to 215, then carry on: 2153 / 644

Advancing to step 6:
The number 644 fits into 2153 3 times, leaving a remainder of 221.
Use 3 as the next digit of our solution. 
Result so far: 953.0
The remainder is 221 after subtracting 1932 from 2153.
Grab the next digit (3) from the dividend, add it to 221, then carry on: 2213 / 644

Let's proceed to step 7:
644 can be fit into 2213 3 times, resulting in a remainder of 281.
The next digit of our result is 3. 
Result so far: 9533.0
If we subtract 1932 from 2213, we get 281.
Bring next digit (2) of the dividend behind the 281 and repeat the process: 2812 / 644

Advancing to step 8:
If we divide 2812 by 644, we get 4 and a remainder of 236.
The next digit of our result is 4. 
Result so far: 95334.0
If we subtract 2576 from 2812, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
When dividing 2360 by 644, we get 3 with a remainder of 428.
Put 3 as the next digit of the answer. 
Result so far: 95334.3
Subtracting 1932 from 2360 leaves us with 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 10:
644 goes into 4280 6 times with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 95334.36
Deduct 3864 from 4280 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 11:
644 can be fit into 4160 6 times, resulting in a remainder of 296.
The next digit of our result is 6. 
Result so far: 95334.366
Subtract 3864 from 4160 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final result is 95334.366 with a remainder of 0.0296.
