We're dividing 99138457 by 117 
We're looking to find how many times 117 goes into 99138457.

Step 1:
If we divide 9 by 117, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 117

Step 2:
117 goes into 99 0 times with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Bring next digit (1) of the dividend behind the 99 and repeat the process: 991 / 117

Moving on to step 3:
117 goes into 991 8 times with a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 936 from 991 to get 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 117

Let's proceed to step 4:
553 divided by 117 is 4 with a remainder of 85.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Deduct 468 from 553 and we're left with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 117

Let's proceed to step 5:
The number 117 fits into 858 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 847.0
If we take 819 away from 858, we end up with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 117

Advancing to step 6:
117 goes into 394 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 8473.0
The remainder is 43 after subtracting 351 from 394.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 117

Let's proceed to step 7:
117 can be fit into 435 3 times, resulting in a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 84733.0
If we take 351 away from 435, we end up with 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 117

Going ahead to step 8:
117 can be fit into 847 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 847337.0
If we take 819 away from 847, 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.

Advancing to step 9:
117 can be fit into 280 2 times, resulting in a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 847337.2
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
The number 117 fits into 460 3 times, leaving a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 847337.23
The remainder is 109 after subtracting 351 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 11:
When dividing 1090 by 117, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 847337.239
Deduct 1053 from 1090 and we're left 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.

Going ahead to step 12:
If we divide 370 by 117, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 847337.2393
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
190 divided by 117 is 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 847337.23931
Subtracting 117 from 190 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 14:
The number 117 fits into 730 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 847337.239316
The remainder is 28 after subtracting 702 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
117 can be fit into 280 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 847337.2393162
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 16:
117 can be fit into 460 3 times, resulting in a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 847337.23931623
If we subtract 351 from 460, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

After the division, we end up with 847337.23931623 and a remainder of 1.09e-07.
