We're dividing 89770903 by 129 
We want to figure out the number of times 89770903 can be divided by 129.

Advancing to step 1:
8 divided by 129 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 129

Going ahead to step 2:
129 goes into 89 0 times with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 129

Step 3:
897 divided by 129 is 6 with a remainder of 123.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 774 from 897 to get 123.
Fetch the next digit (7) from the dividend, attach it to 123 and continue: 1237 / 129

Advancing to step 4:
If we divide 1237 by 129, we get 9 and a remainder of 76.
The next digit of our result is 9. 
Result so far: 69.0
The remainder is 76 after subtracting 1161 from 1237.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 129

On to step 5:
If we divide 760 by 129, we get 5 and a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 695.0
Subtract 645 from 760 to get 115.
Bring next digit (9) of the dividend behind the 115 and repeat the process: 1159 / 129

On to step 6:
1159 divided by 129 is 8 with a remainder of 127.
Write down 8 as next digit of the result. 
Result so far: 6958.0
Subtracting 1032 from 1159 leaves us with 127.
Bring next digit (0) of the dividend behind the 127 and repeat the process: 1270 / 129

Moving on to step 7:
When dividing 1270 by 129, we get 9 with a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 69589.0
If we take 1161 away from 1270, we end up with 109.
Grab the next digit (3) from the dividend, add it to 109, then carry on: 1093 / 129

Moving on to step 8:
1093 divided by 129 is 8 with a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 695898.0
Subtract 1032 from 1093 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
When dividing 610 by 129, we get 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 695898.4
Subtracting 516 from 610 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
When dividing 940 by 129, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 695898.47
Subtracting 903 from 940 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
When dividing 370 by 129, we get 2 with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 695898.472
Subtract 258 from 370 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
If we divide 1120 by 129, we get 8 and a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 695898.4728
Subtract 1032 from 1120 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 13:
If we divide 880 by 129, we get 6 and a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 695898.47286
Subtract 774 from 880 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
1060 divided by 129 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 695898.472868
If we take 1032 away from 1060, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
If we divide 280 by 129, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 695898.4728682
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
The number 129 fits into 220 1 times, leaving a remainder of 91.
The next digit of our result is 1. 
Result so far: 695898.47286821
If we take 129 away from 220, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 695898.47286821 with a remainder of 9.1e-08.
