55294102 divided by 644 
We want to divide 55294102 by 644.

Going ahead to step 1:
The number 644 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 644

Advancing to step 2:
55 divided by 644 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 644

On to step 3:
644 can be fit into 552 0 times, resulting in a remainder of 552.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 552, we get 552.
Fetch the next digit (9) from the dividend, attach it to 552 and continue: 5529 / 644

Let's proceed to step 4:
When dividing 5529 by 644, we get 8 with a remainder of 377.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5152 from 5529, we get 377.
Bring next digit (4) of the dividend behind the 377 and repeat the process: 3774 / 644

Moving on to step 5:
644 goes into 3774 5 times with a remainder of 554.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 3220 away from 3774, we end up with 554.
Fetch the next digit (1) from the dividend, attach it to 554 and continue: 5541 / 644

Going ahead to step 6:
5541 divided by 644 is 8 with a remainder of 389.
Record the quotient 8 as the next digit in the result. 
Result so far: 858.0
The remainder is 389 after subtracting 5152 from 5541.
Grab the next digit (0) from the dividend, add it to 389, then carry on: 3890 / 644

On to step 7:
644 goes into 3890 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 8586.0
Subtracting 3864 from 3890 leaves us with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 644

Moving on to step 8:
262 divided by 644 is 0 with a remainder of 262.
Put 0 as the next digit of the answer. 
Result so far: 85860.0
The remainder is 262 after subtracting 0 from 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 9:
If we divide 2620 by 644, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 85860.4
Deduct 2576 from 2620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
440 divided by 644 is 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 85860.4
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
If we divide 4400 by 644, we get 6 and a remainder of 536.
The next digit of our result is 6. 
Result so far: 85860.406
Subtracting 3864 from 4400 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 12:
The number 644 fits into 5360 8 times, leaving a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 85860.4068
The remainder is 208 after subtracting 5152 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 13:
644 goes into 2080 3 times with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 85860.40683
Deduct 1932 from 2080 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
644 goes into 1480 2 times with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 85860.406832
Subtract 1288 from 1480 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
644 can be fit into 1920 2 times, resulting in a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 85860.4068322
Deduct 1288 from 1920 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Our division results in 85860.4068322 with a remaining 6.32e-06.
