We're dividing 71433027 by 645 
Our goal is to divide 71433027 by 645.

Going ahead to step 1:
7 divided by 645 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 645

Advancing to step 2:
645 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 645

Advancing to step 3:
If we divide 714 by 645, we get 1 and a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 645 from 714 leaves us with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 645

Step 4:
When dividing 693 by 645, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 645 from 693, we get 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 645

On to step 5:
483 divided by 645 is 0 with a remainder of 483.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 483 after subtracting 0 from 483.
Grab the next digit (0) from the dividend, add it to 483, then carry on: 4830 / 645

Going ahead to step 6:
The number 645 fits into 4830 7 times, leaving a remainder of 315.
The number 7 becomes the next digit in our result. 
Result so far: 1107.0
Deduct 4515 from 4830 and we're left with 315.
Append the next digit (2) from the dividend to 315 and continue with: 3152 / 645

Let's proceed to step 7:
645 can be fit into 3152 4 times, resulting in a remainder of 572.
The next digit of our result is 4. 
Result so far: 11074.0
Subtract 2580 from 3152 to get 572.
Take the next digit (7) from the dividend and append it to 572, then repeat: 5727 / 645

On to step 8:
645 can be fit into 5727 8 times, resulting in a remainder of 567.
The number 8 becomes the next digit in our result. 
Result so far: 110748.0
If we subtract 5160 from 5727, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 9:
When dividing 5670 by 645, we get 8 with a remainder of 510.
Put 8 as the next digit of the answer. 
Result so far: 110748.8
Subtracting 5160 from 5670 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
When dividing 5100 by 645, we get 7 with a remainder of 585.
Record the quotient 7 as the next digit in the result. 
Result so far: 110748.87
Subtract 4515 from 5100 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 11:
If we divide 5850 by 645, we get 9 and a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 110748.879
If we take 5805 away from 5850, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
The number 645 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 110748.879
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 13:
When dividing 4500 by 645, we get 6 with a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 110748.87906
If we take 3870 away from 4500, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 14:
If we divide 6300 by 645, we get 9 and a remainder of 495.
Put 9 as the next digit of the answer. 
Result so far: 110748.879069
Subtracting 5805 from 6300 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 15:
4950 divided by 645 is 7 with a remainder of 435.
Put 7 as the next digit of the answer. 
Result so far: 110748.8790697
If we take 4515 away from 4950, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 16:
If we divide 4350 by 645, we get 6 and a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 110748.87906976
If we take 3870 away from 4350, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 110748.87906976, with a leftover of 4.8e-07.
