Let's divide 65489431 by 669
Our goal is to divide 65489431 by 669.

Let's proceed to step 1:
If we divide 6 by 669, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 669

On to step 2:
If we divide 65 by 669, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 669

Moving on to step 3:
654 divided by 669 is 0 with a remainder of 654.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 654 and we're left with 654.
Grab the next digit (8) from the dividend, add it to 654, then carry on: 6548 / 669

Step 4:
669 goes into 6548 9 times with a remainder of 527.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 6021 from 6548 to get 527.
Fetch the next digit (9) from the dividend, attach it to 527 and continue: 5279 / 669

Let's proceed to step 5:
If we divide 5279 by 669, we get 7 and a remainder of 596.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
The remainder is 596 after subtracting 4683 from 5279.
Bring next digit (4) of the dividend behind the 596 and repeat the process: 5964 / 669

Step 6:
669 can be fit into 5964 8 times, resulting in a remainder of 612.
Record the quotient 8 as the next digit in the result. 
Result so far: 978.0
Subtracting 5352 from 5964 leaves us with 612.
Bring next digit (3) of the dividend behind the 612 and repeat the process: 6123 / 669

Step 7:
669 goes into 6123 9 times with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 9789.0
Subtract 6021 from 6123 to get 102.
Take the next digit (1) from the dividend and append it to 102, then repeat: 1021 / 669

On to step 8:
1021 divided by 669 is 1 with a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 97891.0
Deduct 669 from 1021 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 9:
669 goes into 3520 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 97891.5
Deduct 3345 from 3520 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 10:
1750 divided by 669 is 2 with a remainder of 412.
The number 2 becomes the next digit in our result. 
Result so far: 97891.52
Subtracting 1338 from 1750 leaves us with 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:
The number 669 fits into 4120 6 times, leaving a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 97891.526
Subtract 4014 from 4120 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
669 goes into 1060 1 times with a remainder of 391.
Record the quotient 1 as the next digit in the result. 
Result so far: 97891.5261
Subtracting 669 from 1060 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 13:
If we divide 3910 by 669, we get 5 and a remainder of 565.
Record the quotient 5 as the next digit in the result. 
Result so far: 97891.52615
Deduct 3345 from 3910 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

On to step 14:
The number 669 fits into 5650 8 times, leaving a remainder of 298.
The next digit of our result is 8. 
Result so far: 97891.526158
Deduct 5352 from 5650 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 15:
2980 divided by 669 is 4 with a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 97891.5261584
If we subtract 2676 from 2980, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 16:
669 goes into 3040 4 times with a remainder of 364.
The next digit of our result is 4. 
Result so far: 97891.52615844
Subtract 2676 from 3040 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Our division results in 97891.52615844 with a remaining 3.64e-07.
