We look at the division of 31248900 by 669 
Our goal is to divide 31248900 by 669.

Let's proceed to step 1:
When dividing 3 by 669, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 669

Going ahead to step 2:
If we divide 31 by 669, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 669

Step 3:
312 divided by 669 is 0 with a remainder of 312.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 312, we end up with 312.
Grab the next digit (4) from the dividend, add it to 312, then carry on: 3124 / 669

Moving on to step 4:
The number 669 fits into 3124 4 times, leaving a remainder of 448.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2676 away from 3124, we end up with 448.
Fetch the next digit (8) from the dividend, attach it to 448 and continue: 4488 / 669

Moving on to step 5:
669 can be fit into 4488 6 times, resulting in a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 4014 from 4488, we get 474.
Bring next digit (9) of the dividend behind the 474 and repeat the process: 4749 / 669

On to step 6:
If we divide 4749 by 669, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
The remainder is 66 after subtracting 4683 from 4749.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 669

Going ahead to step 7:
669 can be fit into 660 0 times, resulting in a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 4670.0
If we subtract 0 from 660, we get 660.
Append the next digit (0) from the dividend to 660 and continue with: 6600 / 669

Moving on to step 8:
If we divide 6600 by 669, we get 9 and a remainder of 579.
The next digit of our result is 9. 
Result so far: 46709.0
Subtract 6021 from 6600 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Let's proceed to step 9:
When dividing 5790 by 669, we get 8 with a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 46709.8
Subtract 5352 from 5790 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 10:
If we divide 4380 by 669, we get 6 and a remainder of 366.
Record the quotient 6 as the next digit in the result. 
Result so far: 46709.86
Deduct 4014 from 4380 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 11:
When dividing 3660 by 669, we get 5 with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 46709.865
The remainder is 315 after subtracting 3345 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 12:
When dividing 3150 by 669, we get 4 with a remainder of 474.
The number 4 becomes the next digit in our result. 
Result so far: 46709.8654
The remainder is 474 after subtracting 2676 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 13:
4740 divided by 669 is 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 46709.86547
Deduct 4683 from 4740 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
If we divide 570 by 669, we get 0 and a remainder of 570.
The next digit of our result is 0. 
Result so far: 46709.86547
Subtracting 0 from 570 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 15:
The number 669 fits into 5700 8 times, leaving a remainder of 348.
Record the quotient 8 as the next digit in the result. 
Result so far: 46709.8654708
Deduct 5352 from 5700 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 16:
3480 divided by 669 is 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 46709.86547085
The remainder is 135 after subtracting 3345 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final outcome is 46709.86547085, with a leftover of 1.35e-07.
