We look at the division of 78908159 by 853 
Our goal is to divide 78908159 by 853.

Going ahead to step 1:
7 divided by 853 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 853

On to step 2:
853 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 853

Let's proceed to step 3:
853 goes into 789 0 times with a remainder of 789.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 789 to get 789.
Grab the next digit (0) from the dividend, add it to 789, then carry on: 7890 / 853

Step 4:
When dividing 7890 by 853, we get 9 with a remainder of 213.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7677 from 7890 leaves us with 213.
Take the next digit (8) from the dividend and append it to 213, then repeat: 2138 / 853

Let's proceed to step 5:
853 goes into 2138 2 times with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Deduct 1706 from 2138 and we're left with 432.
Include the next digit (1) from the dividend after 432, then repeat: 4321 / 853

Going ahead to step 6:
If we divide 4321 by 853, we get 5 and a remainder of 56.
The next digit of our result is 5. 
Result so far: 925.0
Subtracting 4265 from 4321 leaves us with 56.
Fetch the next digit (5) from the dividend, attach it to 56 and continue: 565 / 853

Moving on to step 7:
The number 853 fits into 565 0 times, leaving a remainder of 565.
Use 0 as the next digit of our solution. 
Result so far: 9250.0
If we subtract 0 from 565, we get 565.
Bring next digit (9) of the dividend behind the 565 and repeat the process: 5659 / 853

Step 8:
The number 853 fits into 5659 6 times, leaving a remainder of 541.
Record the quotient 6 as the next digit in the result. 
Result so far: 92506.0
Subtracting 5118 from 5659 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 9:
When dividing 5410 by 853, we get 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 92506.6
Deduct 5118 from 5410 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 10:
If we divide 2920 by 853, we get 3 and a remainder of 361.
The next digit of our result is 3. 
Result so far: 92506.63
Deduct 2559 from 2920 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 11:
The number 853 fits into 3610 4 times, leaving a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 92506.634
Subtract 3412 from 3610 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 12:
If we divide 1980 by 853, we get 2 and a remainder of 274.
Record the quotient 2 as the next digit in the result. 
Result so far: 92506.6342
If we subtract 1706 from 1980, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 13:
When dividing 2740 by 853, we get 3 with a remainder of 181.
Write down 3 as next digit of the result. 
Result so far: 92506.63423
Subtracting 2559 from 2740 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 14:
1810 divided by 853 is 2 with a remainder of 104.
The next digit of our result is 2. 
Result so far: 92506.634232
The remainder is 104 after subtracting 1706 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 15:
853 can be fit into 1040 1 times, resulting in a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 92506.6342321
Subtract 853 from 1040 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 16:
853 can be fit into 1870 2 times, resulting in a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 92506.63423212
The remainder is 164 after subtracting 1706 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 92506.63423212, with a leftover of 1.64e-07.
