Let's divide 8454515 by 770
Let's see how many times 770 fits into 8454515.

On to step 1:
When dividing 8 by 770, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 770

On to step 2:
770 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (5) from the dividend and append it to 84, then repeat: 845 / 770

Moving on to step 3:
If we divide 845 by 770, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 75 after subtracting 770 from 845.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 770

On to step 4:
The number 770 fits into 754 0 times, leaving a remainder of 754.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 754 and we're left with 754.
Fetch the next digit (5) from the dividend, attach it to 754 and continue: 7545 / 770

On to step 5:
When dividing 7545 by 770, we get 9 with a remainder of 615.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 615 after subtracting 6930 from 7545.
Grab the next digit (1) from the dividend, add it to 615, then carry on: 6151 / 770

Going ahead to step 6:
770 can be fit into 6151 7 times, resulting in a remainder of 761.
The next digit of our result is 7. 
Result so far: 1097.0
Subtract 5390 from 6151 to get 761.
Bring next digit (5) of the dividend behind the 761 and repeat the process: 7615 / 770

Let's proceed to step 7:
When dividing 7615 by 770, we get 9 with a remainder of 685.
Record the quotient 9 as the next digit in the result. 
Result so far: 10979.0
Subtracting 6930 from 7615 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Let's proceed to step 8:
If we divide 6850 by 770, we get 8 and a remainder of 690.
Put 8 as the next digit of the answer. 
Result so far: 10979.8
Subtracting 6160 from 6850 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Let's proceed to step 9:
770 goes into 6900 8 times with a remainder of 740.
Write down 8 as next digit of the result. 
Result so far: 10979.88
Subtracting 6160 from 6900 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

In conclusion, the division gives 10979.88 with a balance of 0.74.
