35907485 ÷ 644 
Let's see how many times 644 fits into 35907485.

Advancing to step 1:
If we divide 3 by 644, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 644

Advancing to step 2:
When dividing 35 by 644, we get 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 644

On to step 3:
644 goes into 359 0 times with a remainder of 359.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 359 to get 359.
Include the next digit (0) from the dividend after 359, then repeat: 3590 / 644

Advancing to step 4:
3590 divided by 644 is 5 with a remainder of 370.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3220 away from 3590, we end up with 370.
Fetch the next digit (7) from the dividend, attach it to 370 and continue: 3707 / 644

Let's proceed to step 5:
644 goes into 3707 5 times with a remainder of 487.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 3220 from 3707, we get 487.
Append the next digit (4) from the dividend to 487 and continue with: 4874 / 644

Let's proceed to step 6:
644 can be fit into 4874 7 times, resulting in a remainder of 366.
Use 7 as the next digit of our solution. 
Result so far: 557.0
Subtracting 4508 from 4874 leaves us with 366.
Fetch the next digit (8) from the dividend, attach it to 366 and continue: 3668 / 644

Moving on to step 7:
644 goes into 3668 5 times with a remainder of 448.
Write down 5 as next digit of the result. 
Result so far: 5575.0
The remainder is 448 after subtracting 3220 from 3668.
Take the next digit (5) from the dividend and append it to 448, then repeat: 4485 / 644

On to step 8:
4485 divided by 644 is 6 with a remainder of 621.
Put 6 as the next digit of the answer. 
Result so far: 55756.0
Deduct 3864 from 4485 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Let's proceed to step 9:
If we divide 6210 by 644, we get 9 and a remainder of 414.
Use 9 as the next digit of our solution. 
Result so far: 55756.9
Deduct 5796 from 6210 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 10:
If we divide 4140 by 644, we get 6 and a remainder of 276.
The next digit of our result is 6. 
Result so far: 55756.96
If we take 3864 away from 4140, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
The number 644 fits into 2760 4 times, leaving a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 55756.964
Subtracting 2576 from 2760 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
1840 divided by 644 is 2 with a remainder of 552.
Put 2 as the next digit of the answer. 
Result so far: 55756.9642
If we subtract 1288 from 1840, we get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 13:
When dividing 5520 by 644, we get 8 with a remainder of 368.
The next digit of our result is 8. 
Result so far: 55756.96428
If we subtract 5152 from 5520, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 14:
644 goes into 3680 5 times with a remainder of 460.
The next digit of our result is 5. 
Result so far: 55756.964285
The remainder is 460 after subtracting 3220 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 15:
The number 644 fits into 4600 7 times, leaving a remainder of 92.
The next digit of our result is 7. 
Result so far: 55756.9642857
Deduct 4508 from 4600 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 16:
644 can be fit into 920 1 times, resulting in a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 55756.96428571
Subtracting 644 from 920 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 55756.96428571, and the remainder is 2.76e-07.
