We divide 33439770 by 645
Our goal is to divide 33439770 by 645.

On to step 1:
If we divide 3 by 645, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 645

Advancing to step 2:
When dividing 33 by 645, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 645

On to step 3:
The number 645 fits into 334 0 times, leaving a remainder of 334.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 334 after subtracting 0 from 334.
Fetch the next digit (3) from the dividend, attach it to 334 and continue: 3343 / 645

On to step 4:
645 goes into 3343 5 times with a remainder of 118.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 3225 from 3343 leaves us with 118.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 645

Moving on to step 5:
The number 645 fits into 1189 1 times, leaving a remainder of 544.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtract 645 from 1189 to get 544.
Include the next digit (7) from the dividend after 544, then repeat: 5447 / 645

Moving on to step 6:
645 can be fit into 5447 8 times, resulting in a remainder of 287.
Record the quotient 8 as the next digit in the result. 
Result so far: 518.0
The remainder is 287 after subtracting 5160 from 5447.
Fetch the next digit (7) from the dividend, attach it to 287 and continue: 2877 / 645

Going ahead to step 7:
If we divide 2877 by 645, we get 4 and a remainder of 297.
Put 4 as the next digit of the answer. 
Result so far: 5184.0
The remainder is 297 after subtracting 2580 from 2877.
Take the next digit (0) from the dividend and append it to 297, then repeat: 2970 / 645

Let's proceed to step 8:
If we divide 2970 by 645, we get 4 and a remainder of 390.
The next digit of our result is 4. 
Result so far: 51844.0
Subtracting 2580 from 2970 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 9:
645 can be fit into 3900 6 times, resulting in a remainder of 30.
The next digit of our result is 6. 
Result so far: 51844.6
Deduct 3870 from 3900 and we're left 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:
645 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 51844.6
Subtract 0 from 300 to 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.

Let's proceed to step 11:
645 can be fit into 3000 4 times, resulting in a remainder of 420.
The next digit of our result is 4. 
Result so far: 51844.604
Subtract 2580 from 3000 to 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.
Put 6 as the next digit of the answer. 
Result so far: 51844.6046
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.

On to step 13:
If we divide 3300 by 645, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 51844.60465
Deduct 3225 from 3300 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
750 divided by 645 is 1 with a remainder of 105.
The next digit of our result is 1. 
Result so far: 51844.604651
Subtract 645 from 750 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 15:
When dividing 1050 by 645, we get 1 with a remainder of 405.
Put 1 as the next digit of the answer. 
Result so far: 51844.6046511
The remainder is 405 after subtracting 645 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final result is 51844.6046511 with a remainder of 4.05e-06.
