We divide 8253179 by 645
We want to figure out the number of times 8253179 can be divided by 645.

Going ahead to step 1:
The number 645 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 645

Step 2:
The number 645 fits into 82 0 times, leaving a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 645

Advancing to step 3:
825 divided by 645 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 645 from 825, we get 180.
Grab the next digit (3) from the dividend, add it to 180, then carry on: 1803 / 645

Going ahead to step 4:
1803 divided by 645 is 2 with a remainder of 513.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1290 from 1803 leaves us with 513.
Bring next digit (1) of the dividend behind the 513 and repeat the process: 5131 / 645

Let's proceed to step 5:
645 goes into 5131 7 times with a remainder of 616.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 4515 from 5131 and we're left with 616.
Take the next digit (7) from the dividend and append it to 616, then repeat: 6167 / 645

On to step 6:
When dividing 6167 by 645, we get 9 with a remainder of 362.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
If we subtract 5805 from 6167, we get 362.
Take the next digit (9) from the dividend and append it to 362, then repeat: 3629 / 645

On to step 7:
If we divide 3629 by 645, we get 5 and a remainder of 404.
Put 5 as the next digit of the answer. 
Result so far: 12795.0
The remainder is 404 after subtracting 3225 from 3629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 8:
The number 645 fits into 4040 6 times, leaving a remainder of 170.
The next digit of our result is 6. 
Result so far: 12795.6
Subtracting 3870 from 4040 leaves us 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.

Advancing to step 9:
645 goes into 1700 2 times with a remainder of 410.
Put 2 as the next digit of the answer. 
Result so far: 12795.62
Deduct 1290 from 1700 and we're left 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.

Let's proceed to step 10:
If we divide 4100 by 645, we get 6 and a remainder of 230.
Write down 6 as next digit of the result. 
Result so far: 12795.626
Deduct 3870 from 4100 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
2300 divided by 645 is 3 with a remainder of 365.
The next digit of our result is 3. 
Result so far: 12795.6263
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.

Moving on to step 12:
645 goes into 3650 5 times with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 12795.62635
Subtract 3225 from 3650 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 13:
645 can be fit into 4250 6 times, resulting in a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 12795.626356
The remainder is 380 after subtracting 3870 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
645 can be fit into 3800 5 times, resulting in a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 12795.6263565
If we subtract 3225 from 3800, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Let's proceed to step 15:
When dividing 5750 by 645, we get 8 with a remainder of 590.
Put 8 as the next digit of the answer. 
Result so far: 12795.62635658
Deduct 5160 from 5750 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 12795.62635658, with a leftover of 5.9e-07.
