29532489 ÷ 645 
We want to divide 29532489 by 645.

Going ahead to step 1:
When dividing 2 by 645, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 645

Going ahead to step 2:
29 divided by 645 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 645

Let's proceed to step 3:
645 can be fit into 295 0 times, resulting in a remainder of 295.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 295, we get 295.
Fetch the next digit (3) from the dividend, attach it to 295 and continue: 2953 / 645

Advancing to step 4:
2953 divided by 645 is 4 with a remainder of 373.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2580 from 2953, we get 373.
Fetch the next digit (2) from the dividend, attach it to 373 and continue: 3732 / 645

Going ahead to step 5:
If we divide 3732 by 645, we get 5 and a remainder of 507.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 3225 from 3732 to get 507.
Take the next digit (4) from the dividend and append it to 507, then repeat: 5074 / 645

On to step 6:
5074 divided by 645 is 7 with a remainder of 559.
Record the quotient 7 as the next digit in the result. 
Result so far: 457.0
The remainder is 559 after subtracting 4515 from 5074.
Append the next digit (8) from the dividend to 559 and continue with: 5598 / 645

Let's proceed to step 7:
When dividing 5598 by 645, we get 8 with a remainder of 438.
Record the quotient 8 as the next digit in the result. 
Result so far: 4578.0
Deduct 5160 from 5598 and we're left with 438.
Append the next digit (9) from the dividend to 438 and continue with: 4389 / 645

Moving on to step 8:
The number 645 fits into 4389 6 times, leaving a remainder of 519.
Use 6 as the next digit of our solution. 
Result so far: 45786.0
Subtract 3870 from 4389 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 9:
If we divide 5190 by 645, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 45786.8
Subtracting 5160 from 5190 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 645 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 45786.8
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
645 goes into 3000 4 times with a remainder of 420.
Put 4 as the next digit of the answer. 
Result so far: 45786.804
If we subtract 2580 from 3000, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 12:
645 goes into 4200 6 times with a remainder of 330.
Write down 6 as next digit of the result. 
Result so far: 45786.8046
Subtracting 3870 from 4200 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 13:
645 can be fit into 3300 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 45786.80465
The remainder is 75 after subtracting 3225 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
645 goes into 750 1 times with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 45786.804651
Subtracting 645 from 750 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 15:
If we divide 1050 by 645, we get 1 and a remainder of 405.
Record the quotient 1 as the next digit in the result. 
Result so far: 45786.8046511
Deduct 645 from 1050 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Our division results in 45786.8046511 with a remaining 4.05e-06.
