645 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 645

Moving on to step 2:
The number 645 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 645

Let's proceed to step 3:
788 divided by 645 is 1 with a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 645 away from 788, we end up with 143.

On to step 4:
The number 645 fits into 1434 2 times, leaving a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1290 away from 1434, we end up with 144.
Fetch the next digit (9) from the dividend, attach it to 144 and continue: 1449 / 645

Advancing to step 5:
If we divide 1449 by 645, we get 2 and a remainder of 159.
The next digit of our result is 2. 
Result so far: 122.0
The remainder is 159 after subtracting 1290 from 1449.
Take the next digit (6) from the dividend and append it to 159, then repeat: 1596 / 645

Going ahead to step 6:
The number 645 fits into 1596 2 times, leaving a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 1222.0
Subtract 1290 from 1596 to get 306.
Grab the next digit (8) from the dividend, add it to 306, then carry on: 3068 / 645

On to step 7:
645 goes into 3068 4 times with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 12224.0
If we subtract 2580 from 3068, we get 488.
Include the next digit (3) from the dividend after 488, then repeat: 4883 / 645

Advancing to step 8:
If we divide 4883 by 645, we get 7 and a remainder of 368.
Put 7 as the next digit of the answer. 
Result so far: 122247.0
Subtract 4515 from 4883 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 9:
645 can be fit into 3680 5 times, resulting in a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 122247.5
Subtract 3225 from 3680 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 10:
The number 645 fits into 4550 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 122247.57
The remainder is 35 after subtracting 4515 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
If we divide 350 by 645, we get 0 and a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 122247.57
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
If we divide 3500 by 645, we get 5 and a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 122247.5705
If we subtract 3225 from 3500, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 13:
2750 divided by 645 is 4 with a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 122247.57054
If we take 2580 away from 2750, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
1700 divided by 645 is 2 with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 122247.570542
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.

Step 15:
4100 divided by 645 is 6 with a remainder of 230.
Record the quotient 6 as the next digit in the result. 
Result so far: 122247.5705426
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.

Step 16:
If we divide 2300 by 645, we get 3 and a remainder of 365.
Use 3 as the next digit of our solution. 
Result so far: 122247.57054263
Deduct 1935 from 2300 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The quotient of the division is 122247.57054263, and the remainder is 3.65e-07.
