We divide 31535544 by 669
We want to figure out the number of times 31535544 can be divided by 669.

On to step 1:
When dividing 3 by 669, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 669

Advancing to step 2:
When dividing 31 by 669, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 669

Step 3:
If we divide 315 by 669, we get 0 and a remainder of 315.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Grab the next digit (3) from the dividend, add it to 315, then carry on: 3153 / 669

Let's proceed to step 4:
669 can be fit into 3153 4 times, resulting in a remainder of 477.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2676 from 3153, we get 477.
Append the next digit (5) from the dividend to 477 and continue with: 4775 / 669

Moving on to step 5:
The number 669 fits into 4775 7 times, leaving a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 4683 away from 4775, we end up with 92.
Grab the next digit (5) from the dividend, add it to 92, then carry on: 925 / 669

Moving on to step 6:
When dividing 925 by 669, we get 1 with a remainder of 256.
The next digit of our result is 1. 
Result so far: 471.0
Subtracting 669 from 925 leaves us with 256.
Fetch the next digit (4) from the dividend, attach it to 256 and continue: 2564 / 669

Moving on to step 7:
669 can be fit into 2564 3 times, resulting in a remainder of 557.
Write down 3 as next digit of the result. 
Result so far: 4713.0
The remainder is 557 after subtracting 2007 from 2564.
Bring next digit (4) of the dividend behind the 557 and repeat the process: 5574 / 669

Step 8:
669 can be fit into 5574 8 times, resulting in a remainder of 222.
Record the quotient 8 as the next digit in the result. 
Result so far: 47138.0
Subtracting 5352 from 5574 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 9:
The number 669 fits into 2220 3 times, leaving a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 47138.3
Deduct 2007 from 2220 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 10:
If we divide 2130 by 669, we get 3 and a remainder of 123.
The next digit of our result is 3. 
Result so far: 47138.33
Deduct 2007 from 2130 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The quotient of the division is 47138.33, and the remainder is 0.123.
