We look at the division of 84815068 by 646 
We want to divide 84815068 by 646.

Going ahead to step 1:
If we divide 8 by 646, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 646

Going ahead to step 2:
If we divide 84 by 646, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Append the next digit (8) from the dividend to 84 and continue with: 848 / 646

Going ahead to step 3:
646 can be fit into 848 1 times, resulting in a remainder of 202.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 646 from 848 and we're left with 202.
Grab the next digit (1) from the dividend, add it to 202, then carry on: 2021 / 646

Let's proceed to step 4:
646 goes into 2021 3 times with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 83 after subtracting 1938 from 2021.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 646

On to step 5:
The number 646 fits into 835 1 times, leaving a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we take 646 away from 835, we end up with 189.
Fetch the next digit (0) from the dividend, attach it to 189 and continue: 1890 / 646

Advancing to step 6:
646 can be fit into 1890 2 times, resulting in a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 1312.0
If we subtract 1292 from 1890, we get 598.
Bring next digit (6) of the dividend behind the 598 and repeat the process: 5986 / 646

On to step 7:
646 can be fit into 5986 9 times, resulting in a remainder of 172.
The next digit of our result is 9. 
Result so far: 13129.0
If we take 5814 away from 5986, we end up with 172.
Append the next digit (8) from the dividend to 172 and continue with: 1728 / 646

Advancing to step 8:
646 goes into 1728 2 times with a remainder of 436.
Record the quotient 2 as the next digit in the result. 
Result so far: 131292.0
Deduct 1292 from 1728 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 9:
If we divide 4360 by 646, we get 6 and a remainder of 484.
The next digit of our result is 6. 
Result so far: 131292.6
If we take 3876 away from 4360, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 10:
4840 divided by 646 is 7 with a remainder of 318.
The number 7 becomes the next digit in our result. 
Result so far: 131292.67
If we subtract 4522 from 4840, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 11:
646 can be fit into 3180 4 times, resulting in a remainder of 596.
Use 4 as the next digit of our solution. 
Result so far: 131292.674
The remainder is 596 after subtracting 2584 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 12:
When dividing 5960 by 646, we get 9 with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 131292.6749
Subtract 5814 from 5960 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 13:
When dividing 1460 by 646, we get 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 131292.67492
Subtract 1292 from 1460 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 14:
If we divide 1680 by 646, we get 2 and a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 131292.674922
If we subtract 1292 from 1680, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 131292.674922 with a remaining 3.88e-05.
