We're dividing 68852245 by 645 
Our goal is to divide 68852245 by 645.

On to step 1:
If we divide 6 by 645, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 645

Step 2:
68 divided by 645 is 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 645

Step 3:
688 divided by 645 is 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 645 from 688 leaves us with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 645

Advancing to step 4:
If we divide 435 by 645, we get 0 and a remainder of 435.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 435 and we're left with 435.
Append the next digit (2) from the dividend to 435 and continue with: 4352 / 645

Let's proceed to step 5:
645 goes into 4352 6 times with a remainder of 482.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
The remainder is 482 after subtracting 3870 from 4352.
Grab the next digit (2) from the dividend, add it to 482, then carry on: 4822 / 645

Let's proceed to step 6:
When dividing 4822 by 645, we get 7 with a remainder of 307.
The next digit of our result is 7. 
Result so far: 1067.0
If we take 4515 away from 4822, we end up with 307.
Bring next digit (4) of the dividend behind the 307 and repeat the process: 3074 / 645

Moving on to step 7:
645 goes into 3074 4 times with a remainder of 494.
The next digit of our result is 4. 
Result so far: 10674.0
If we subtract 2580 from 3074, we get 494.
Grab the next digit (5) from the dividend, add it to 494, then carry on: 4945 / 645

Let's proceed to step 8:
645 can be fit into 4945 7 times, resulting in a remainder of 430.
Write down 7 as next digit of the result. 
Result so far: 106747.0
Subtracting 4515 from 4945 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 9:
645 can be fit into 4300 6 times, resulting in a remainder of 430.
The next digit of our result is 6. 
Result so far: 106747.6
The remainder is 430 after subtracting 3870 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
The number 645 fits into 4300 6 times, leaving a remainder of 430.
The next digit of our result is 6. 
Result so far: 106747.66
The remainder is 430 after subtracting 3870 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final result is 106747.66 with a remainder of 0.43.
