Let's divide 7147779 by 851
Let's see how many times 851 fits into 7147779.

Going ahead to step 1:
7 divided by 851 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 851

On to step 2:
851 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 851

Going ahead to step 3:
714 divided by 851 is 0 with a remainder of 714.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 714 leaves us with 714.
Fetch the next digit (7) from the dividend, attach it to 714 and continue: 7147 / 851

Advancing to step 4:
The number 851 fits into 7147 8 times, leaving a remainder of 339.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6808 from 7147 to get 339.
Include the next digit (7) from the dividend after 339, then repeat: 3397 / 851

On to step 5:
The number 851 fits into 3397 3 times, leaving a remainder of 844.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 2553 away from 3397, we end up with 844.
Fetch the next digit (7) from the dividend, attach it to 844 and continue: 8447 / 851

Advancing to step 6:
8447 divided by 851 is 9 with a remainder of 788.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
Subtract 7659 from 8447 to get 788.
Append the next digit (9) from the dividend to 788 and continue with: 7889 / 851

Step 7:
851 can be fit into 7889 9 times, resulting in a remainder of 230.
The number 9 becomes the next digit in our result. 
Result so far: 8399.0
The remainder is 230 after subtracting 7659 from 7889.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 8:
When dividing 2300 by 851, we get 2 with a remainder of 598.
Put 2 as the next digit of the answer. 
Result so far: 8399.2
If we subtract 1702 from 2300, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 9:
5980 divided by 851 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8399.27
Subtract 5957 from 5980 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
851 goes into 230 0 times with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 8399.27
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
If we divide 2300 by 851, we get 2 and a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 8399.2702
If we take 1702 away from 2300, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 12:
851 goes into 5980 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 8399.27027
Subtracting 5957 from 5980 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
If we divide 230 by 851, we get 0 and a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 8399.27027
The remainder is 230 after subtracting 0 from 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 14:
The number 851 fits into 2300 2 times, leaving a remainder of 598.
The next digit of our result is 2. 
Result so far: 8399.2702702
Subtract 1702 from 2300 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 15:
5980 divided by 851 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 8399.27027027
If we take 5957 away from 5980, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 8399.27027027 with a remainder of 2.3e-08.
