We're dividing 88870589 by 770 
Our goal is to divide 88870589 by 770.

Moving on to step 1:
The number 770 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 770

Going ahead to step 2:
When dividing 88 by 770, we get 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 770

Step 3:
The number 770 fits into 888 1 times, leaving a remainder of 118.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 118 after subtracting 770 from 888.
Include the next digit (7) from the dividend after 118, then repeat: 1187 / 770

Let's proceed to step 4:
770 can be fit into 1187 1 times, resulting in a remainder of 417.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 770 from 1187, we get 417.
Bring next digit (0) of the dividend behind the 417 and repeat the process: 4170 / 770

Advancing to step 5:
If we divide 4170 by 770, we get 5 and a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we subtract 3850 from 4170, we get 320.
Bring next digit (5) of the dividend behind the 320 and repeat the process: 3205 / 770

Advancing to step 6:
3205 divided by 770 is 4 with a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 1154.0
Subtracting 3080 from 3205 leaves us with 125.
Include the next digit (8) from the dividend after 125, then repeat: 1258 / 770

Let's proceed to step 7:
770 goes into 1258 1 times with a remainder of 488.
The next digit of our result is 1. 
Result so far: 11541.0
If we take 770 away from 1258, we end up with 488.
Append the next digit (9) from the dividend to 488 and continue with: 4889 / 770

Advancing to step 8:
770 goes into 4889 6 times with a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 115416.0
Subtract 4620 from 4889 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
The number 770 fits into 2690 3 times, leaving a remainder of 380.
Put 3 as the next digit of the answer. 
Result so far: 115416.3
Deduct 2310 from 2690 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
The number 770 fits into 3800 4 times, leaving a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 115416.34
The remainder is 720 after subtracting 3080 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 11:
The number 770 fits into 7200 9 times, leaving a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 115416.349
Deduct 6930 from 7200 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.

Going ahead to step 12:
If we divide 2700 by 770, we get 3 and a remainder of 390.
The next digit of our result is 3. 
Result so far: 115416.3493
Deduct 2310 from 2700 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
The number 770 fits into 3900 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 115416.34935
If we take 3850 away from 3900, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
When dividing 500 by 770, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 115416.34935
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 15:
5000 divided by 770 is 6 with a remainder of 380.
Use 6 as the next digit of our solution. 
Result so far: 115416.3493506
Subtracting 4620 from 5000 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 16:
If we divide 3800 by 770, we get 4 and a remainder of 720.
Use 4 as the next digit of our solution. 
Result so far: 115416.34935064
Deduct 3080 from 3800 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final result is 115416.34935064 with a remainder of 7.2e-07.
