We divide 84245490 by 645
Let's see how many times 645 fits into 84245490.

Going ahead to step 1:
645 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 645

Let's proceed to step 2:
645 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 645

On to step 3:
The number 645 fits into 842 1 times, leaving a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 645 from 842 leaves us with 197.
Include the next digit (4) from the dividend after 197, then repeat: 1974 / 645

Going ahead to step 4:
The number 645 fits into 1974 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1935 from 1974 and we're left with 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 645

Advancing to step 5:
395 divided by 645 is 0 with a remainder of 395.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we subtract 0 from 395, we get 395.
Fetch the next digit (4) from the dividend, attach it to 395 and continue: 3954 / 645

Let's proceed to step 6:
3954 divided by 645 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 1306.0
Deduct 3870 from 3954 and we're left with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 645

Advancing to step 7:
645 goes into 849 1 times with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 13061.0
Subtracting 645 from 849 leaves us with 204.
Append the next digit (0) from the dividend to 204 and continue with: 2040 / 645

On to step 8:
645 goes into 2040 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 130613.0
If we take 1935 away from 2040, we end up with 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 9:
If we divide 1050 by 645, we get 1 and a remainder of 405.
The next digit of our result is 1. 
Result so far: 130613.1
If we take 645 away from 1050, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 10:
645 can be fit into 4050 6 times, resulting in a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 130613.16
If we take 3870 away from 4050, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
If we divide 1800 by 645, we get 2 and a remainder of 510.
Use 2 as the next digit of our solution. 
Result so far: 130613.162
Subtracting 1290 from 1800 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.

On to step 12:
The number 645 fits into 5100 7 times, leaving a remainder of 585.
The number 7 becomes the next digit in our result. 
Result so far: 130613.1627
The remainder is 585 after subtracting 4515 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 13:
645 goes into 5850 9 times with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 130613.16279
The remainder is 45 after subtracting 5805 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
If we divide 450 by 645, we get 0 and a remainder of 450.
The next digit of our result is 0. 
Result so far: 130613.16279
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
645 goes into 4500 6 times with a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 130613.1627906
The remainder is 630 after subtracting 3870 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 16:
645 can be fit into 6300 9 times, resulting in a remainder of 495.
Write down 9 as next digit of the result. 
Result so far: 130613.16279069
If we subtract 5805 from 6300, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Our division results in 130613.16279069 with a remaining 4.95e-07.
