Let's divide 87970810 by 155
We want to figure out the number of times 87970810 can be divided by 155.

Step 1:
8 divided by 155 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 155

Step 2:
When dividing 87 by 155, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 155

Advancing to step 3:
155 goes into 879 5 times with a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 775 from 879 to get 104.
Append the next digit (7) from the dividend to 104 and continue with: 1047 / 155

Going ahead to step 4:
If we divide 1047 by 155, we get 6 and a remainder of 117.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 930 from 1047, we get 117.
Append the next digit (0) from the dividend to 117 and continue with: 1170 / 155

On to step 5:
The number 155 fits into 1170 7 times, leaving a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 567.0
If we subtract 1085 from 1170, we get 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 155

Going ahead to step 6:
858 divided by 155 is 5 with a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 5675.0
The remainder is 83 after subtracting 775 from 858.
Include the next digit (1) from the dividend after 83, then repeat: 831 / 155

Moving on to step 7:
If we divide 831 by 155, we get 5 and a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 56755.0
The remainder is 56 after subtracting 775 from 831.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 155

Advancing to step 8:
The number 155 fits into 560 3 times, leaving a remainder of 95.
The next digit of our result is 3. 
Result so far: 567553.0
Subtracting 465 from 560 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 9:
155 can be fit into 950 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 567553.6
If we subtract 930 from 950, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
155 goes into 200 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 567553.61
If we take 155 away from 200, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
450 divided by 155 is 2 with a remainder of 140.
The next digit of our result is 2. 
Result so far: 567553.612
If we take 310 away from 450, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 155 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 567553.6129
Subtracting 1395 from 1400 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 155 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 567553.6129
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
If we divide 500 by 155, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 567553.612903
Deduct 465 from 500 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 15:
The number 155 fits into 350 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 567553.6129032
If we take 310 away from 350, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
When dividing 400 by 155, we get 2 with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 567553.61290322
Subtract 310 from 400 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 567553.61290322 with a remaining 9e-08.
