70233115 ÷ 770 
Our goal is to divide 70233115 by 770.

Going ahead to step 1:
770 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 770

On to step 2:
The number 770 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 770

Let's proceed to step 3:
When dividing 702 by 770, we get 0 with a remainder of 702.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 702 to get 702.
Bring next digit (3) of the dividend behind the 702 and repeat the process: 7023 / 770

Moving on to step 4:
7023 divided by 770 is 9 with a remainder of 93.
The next digit of our result is 9. 
Result so far: 9.0
If we take 6930 away from 7023, we end up with 93.
Fetch the next digit (3) from the dividend, attach it to 93 and continue: 933 / 770

Step 5:
If we divide 933 by 770, we get 1 and a remainder of 163.
The next digit of our result is 1. 
Result so far: 91.0
If we subtract 770 from 933, we get 163.
Bring next digit (1) of the dividend behind the 163 and repeat the process: 1631 / 770

Advancing to step 6:
1631 divided by 770 is 2 with a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 912.0
If we take 1540 away from 1631, we end up with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 770

Step 7:
If we divide 911 by 770, we get 1 and a remainder of 141.
The next digit of our result is 1. 
Result so far: 9121.0
Subtracting 770 from 911 leaves us with 141.
Bring next digit (5) of the dividend behind the 141 and repeat the process: 1415 / 770

Step 8:
If we divide 1415 by 770, we get 1 and a remainder of 645.
Record the quotient 1 as the next digit in the result. 
Result so far: 91211.0
If we subtract 770 from 1415, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Step 9:
770 goes into 6450 8 times with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 91211.8
Deduct 6160 from 6450 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
The number 770 fits into 2900 3 times, leaving a remainder of 590.
Write down 3 as next digit of the result. 
Result so far: 91211.83
The remainder is 590 after subtracting 2310 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 11:
The number 770 fits into 5900 7 times, leaving a remainder of 510.
Use 7 as the next digit of our solution. 
Result so far: 91211.837
Subtract 5390 from 5900 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 12:
770 goes into 5100 6 times with a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 91211.8376
If we take 4620 away from 5100, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 13:
770 can be fit into 4800 6 times, resulting in a remainder of 180.
The next digit of our result is 6. 
Result so far: 91211.83766
Deduct 4620 from 4800 and we're left with 180.
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 91211.83766 with a remaining 0.00018.
