35284294 divided by 644 
We want to divide 35284294 by 644.

Advancing to step 1:
The number 644 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 644

Step 2:
644 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 644

Going ahead to step 3:
When dividing 352 by 644, we get 0 with a remainder of 352.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 352 after subtracting 0 from 352.
Bring next digit (8) of the dividend behind the 352 and repeat the process: 3528 / 644

Moving on to step 4:
If we divide 3528 by 644, we get 5 and a remainder of 308.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 3220 from 3528 to get 308.
Grab the next digit (4) from the dividend, add it to 308, then carry on: 3084 / 644

Going ahead to step 5:
If we divide 3084 by 644, we get 4 and a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
The remainder is 508 after subtracting 2576 from 3084.
Append the next digit (2) from the dividend to 508 and continue with: 5082 / 644

On to step 6:
The number 644 fits into 5082 7 times, leaving a remainder of 574.
Write down 7 as next digit of the result. 
Result so far: 547.0
Deduct 4508 from 5082 and we're left with 574.
Bring next digit (9) of the dividend behind the 574 and repeat the process: 5749 / 644

Moving on to step 7:
644 goes into 5749 8 times with a remainder of 597.
Record the quotient 8 as the next digit in the result. 
Result so far: 5478.0
If we subtract 5152 from 5749, we get 597.
Grab the next digit (4) from the dividend, add it to 597, then carry on: 5974 / 644

Advancing to step 8:
644 goes into 5974 9 times with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 54789.0
Deduct 5796 from 5974 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 9:
If we divide 1780 by 644, we get 2 and a remainder of 492.
Record the quotient 2 as the next digit in the result. 
Result so far: 54789.2
If we subtract 1288 from 1780, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 10:
644 can be fit into 4920 7 times, resulting in a remainder of 412.
Put 7 as the next digit of the answer. 
Result so far: 54789.27
If we subtract 4508 from 4920, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 11:
If we divide 4120 by 644, we get 6 and a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 54789.276
If we subtract 3864 from 4120, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 12:
When dividing 2560 by 644, we get 3 with a remainder of 628.
The next digit of our result is 3. 
Result so far: 54789.2763
If we subtract 1932 from 2560, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Step 13:
When dividing 6280 by 644, we get 9 with a remainder of 484.
The next digit of our result is 9. 
Result so far: 54789.27639
Subtracting 5796 from 6280 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 14:
When dividing 4840 by 644, we get 7 with a remainder of 332.
Record the quotient 7 as the next digit in the result. 
Result so far: 54789.276397
The remainder is 332 after subtracting 4508 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 15:
3320 divided by 644 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 54789.2763975
Subtract 3220 from 3320 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 16:
The number 644 fits into 1000 1 times, leaving a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 54789.27639751
The remainder is 356 after subtracting 644 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 54789.27639751 and a remainder of 3.56e-07.
