We divide 77092959 by 840
We want to divide 77092959 by 840.

Advancing to step 1:
840 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 840

On to step 2:
840 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 840

Step 3:
If we divide 770 by 840, we get 0 and a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 770 leaves us with 770.
Append the next digit (9) from the dividend to 770 and continue with: 7709 / 840

Let's proceed to step 4:
The number 840 fits into 7709 9 times, leaving a remainder of 149.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7560 from 7709 and we're left with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 840

Advancing to step 5:
1492 divided by 840 is 1 with a remainder of 652.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 840 from 1492, we get 652.
Bring next digit (9) of the dividend behind the 652 and repeat the process: 6529 / 840

Step 6:
If we divide 6529 by 840, we get 7 and a remainder of 649.
Record the quotient 7 as the next digit in the result. 
Result so far: 917.0
If we take 5880 away from 6529, we end up with 649.
Take the next digit (5) from the dividend and append it to 649, then repeat: 6495 / 840

Going ahead to step 7:
6495 divided by 840 is 7 with a remainder of 615.
The number 7 becomes the next digit in our result. 
Result so far: 9177.0
Subtracting 5880 from 6495 leaves us with 615.
Include the next digit (9) from the dividend after 615, then repeat: 6159 / 840

Let's proceed to step 8:
If we divide 6159 by 840, we get 7 and a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 91777.0
Subtract 5880 from 6159 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 9:
The number 840 fits into 2790 3 times, leaving a remainder of 270.
The number 3 becomes the next digit in our result. 
Result so far: 91777.3
Deduct 2520 from 2790 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
840 can be fit into 2700 3 times, resulting in a remainder of 180.
Use 3 as the next digit of our solution. 
Result so far: 91777.33
The remainder is 180 after subtracting 2520 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 91777.33 with a remaining 0.18.
