We're dividing 68566835 by 645 
Our goal is to divide 68566835 by 645.

Moving on to step 1:
6 divided by 645 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 645

Going ahead to step 2:
If we divide 68 by 645, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 645

Going ahead to step 3:
645 goes into 685 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 645 from 685 to get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 645

Going ahead to step 4:
645 can be fit into 406 0 times, resulting in a remainder of 406.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 406, we end up with 406.
Take the next digit (6) from the dividend and append it to 406, then repeat: 4066 / 645

Let's proceed to step 5:
If we divide 4066 by 645, we get 6 and a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 3870 from 4066 leaves us with 196.
Take the next digit (8) from the dividend and append it to 196, then repeat: 1968 / 645

Step 6:
1968 divided by 645 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 1063.0
The remainder is 33 after subtracting 1935 from 1968.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 645

Step 7:
645 goes into 333 0 times with a remainder of 333.
The next digit of our result is 0. 
Result so far: 10630.0
The remainder is 333 after subtracting 0 from 333.
Fetch the next digit (5) from the dividend, attach it to 333 and continue: 3335 / 645

Advancing to step 8:
645 can be fit into 3335 5 times, resulting in a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 106305.0
The remainder is 110 after subtracting 3225 from 3335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 9:
645 goes into 1100 1 times with a remainder of 455.
The next digit of our result is 1. 
Result so far: 106305.1
Deduct 645 from 1100 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 10:
If we divide 4550 by 645, we get 7 and a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 106305.17
Subtracting 4515 from 4550 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
350 divided by 645 is 0 with a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 106305.17
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 12:
If we divide 3500 by 645, we get 5 and a remainder of 275.
The next digit of our result is 5. 
Result so far: 106305.1705
Deduct 3225 from 3500 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 13:
The number 645 fits into 2750 4 times, leaving a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 106305.17054
The remainder is 170 after subtracting 2580 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
If we divide 1700 by 645, we get 2 and a remainder of 410.
Put 2 as the next digit of the answer. 
Result so far: 106305.170542
If we take 1290 away from 1700, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 15:
If we divide 4100 by 645, we get 6 and a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 106305.1705426
Subtract 3870 from 4100 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
When dividing 2300 by 645, we get 3 with a remainder of 365.
The next digit of our result is 3. 
Result so far: 106305.17054263
The remainder is 365 after subtracting 1935 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 106305.17054263 and a remainder of 3.65e-07.
