91660789 divided by 917 
Our goal is to divide 91660789 by 917.

Advancing to step 1:
When dividing 9 by 917, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 917

Advancing to step 2:
917 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 917

Step 3:
917 goes into 916 0 times with a remainder of 916.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 916, we end up with 916.
Include the next digit (6) from the dividend after 916, then repeat: 9166 / 917

Step 4:
9166 divided by 917 is 9 with a remainder of 913.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 8253 from 9166, we get 913.
Take the next digit (0) from the dividend and append it to 913, then repeat: 9130 / 917

Going ahead to step 5:
9130 divided by 917 is 9 with a remainder of 877.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 8253 from 9130, we get 877.
Append the next digit (7) from the dividend to 877 and continue with: 8777 / 917

Advancing to step 6:
When dividing 8777 by 917, we get 9 with a remainder of 524.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
Deduct 8253 from 8777 and we're left with 524.
Grab the next digit (8) from the dividend, add it to 524, then carry on: 5248 / 917

On to step 7:
If we divide 5248 by 917, we get 5 and a remainder of 663.
The number 5 becomes the next digit in our result. 
Result so far: 9995.0
If we take 4585 away from 5248, we end up with 663.
Fetch the next digit (9) from the dividend, attach it to 663 and continue: 6639 / 917

Let's proceed to step 8:
917 can be fit into 6639 7 times, resulting in a remainder of 220.
The next digit of our result is 7. 
Result so far: 99957.0
Subtract 6419 from 6639 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 9:
917 goes into 2200 2 times with a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 99957.2
Subtracting 1834 from 2200 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 10:
The number 917 fits into 3660 3 times, leaving a remainder of 909.
Use 3 as the next digit of our solution. 
Result so far: 99957.23
If we take 2751 away from 3660, we end up with 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

Moving on to step 11:
917 can be fit into 9090 9 times, resulting in a remainder of 837.
Put 9 as the next digit of the answer. 
Result so far: 99957.239
If we take 8253 away from 9090, we end up with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

On to step 12:
When dividing 8370 by 917, we get 9 with a remainder of 117.
Put 9 as the next digit of the answer. 
Result so far: 99957.2399
Subtract 8253 from 8370 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Our division results in 99957.2399 with a remaining 0.00117.
