85488587 divided by 770 
Our goal is to divide 85488587 by 770.

Step 1:
8 divided by 770 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 770

Advancing to step 2:
85 divided by 770 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 770

Moving on to step 3:
770 goes into 854 1 times with a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 770 from 854 to get 84.
Take the next digit (8) from the dividend and append it to 84, then repeat: 848 / 770

Step 4:
770 goes into 848 1 times with a remainder of 78.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 770 from 848, we get 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 770

On to step 5:
770 can be fit into 788 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we take 770 away from 788, we end up with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 770

Let's proceed to step 6:
770 can be fit into 185 0 times, resulting in a remainder of 185.
Write down 0 as next digit of the result. 
Result so far: 1110.0
If we take 0 away from 185, we end up with 185.
Append the next digit (8) from the dividend to 185 and continue with: 1858 / 770

Moving on to step 7:
When dividing 1858 by 770, we get 2 with a remainder of 318.
Use 2 as the next digit of our solution. 
Result so far: 11102.0
Deduct 1540 from 1858 and we're left with 318.
Include the next digit (7) from the dividend after 318, then repeat: 3187 / 770

Step 8:
If we divide 3187 by 770, we get 4 and a remainder of 107.
Put 4 as the next digit of the answer. 
Result so far: 111024.0
Deduct 3080 from 3187 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
1070 divided by 770 is 1 with a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 111024.1
The remainder is 300 after subtracting 770 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
770 can be fit into 3000 3 times, resulting in a remainder of 690.
The number 3 becomes the next digit in our result. 
Result so far: 111024.13
If we subtract 2310 from 3000, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 11:
770 can be fit into 6900 8 times, resulting in a remainder of 740.
Write down 8 as next digit of the result. 
Result so far: 111024.138
The remainder is 740 after subtracting 6160 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 12:
The number 770 fits into 7400 9 times, leaving a remainder of 470.
The number 9 becomes the next digit in our result. 
Result so far: 111024.1389
Subtract 6930 from 7400 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 13:
770 goes into 4700 6 times with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 111024.13896
Subtract 4620 from 4700 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
770 goes into 800 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 111024.138961
Subtracting 770 from 800 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
770 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 111024.138961
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
770 goes into 3000 3 times with a remainder of 690.
Record the quotient 3 as the next digit in the result. 
Result so far: 111024.13896103
Subtract 2310 from 3000 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The final outcome is 111024.13896103, with a leftover of 6.9e-07.
