We're dividing 99578789 by 781 
Let's see how many times 781 fits into 99578789.

Moving on to step 1:
The number 781 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 781

Step 2:
The number 781 fits into 99 0 times, leaving a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (5) from the dividend to 99 and continue with: 995 / 781

Advancing to step 3:
When dividing 995 by 781, we get 1 with a remainder of 214.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 781 from 995 and we're left with 214.
Fetch the next digit (7) from the dividend, attach it to 214 and continue: 2147 / 781

Moving on to step 4:
781 goes into 2147 2 times with a remainder of 585.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1562 from 2147, we get 585.
Include the next digit (8) from the dividend after 585, then repeat: 5858 / 781

Let's proceed to step 5:
5858 divided by 781 is 7 with a remainder of 391.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtracting 5467 from 5858 leaves us with 391.
Grab the next digit (7) from the dividend, add it to 391, then carry on: 3917 / 781

Moving on to step 6:
781 goes into 3917 5 times with a remainder of 12.
The next digit of our result is 5. 
Result so far: 1275.0
Subtract 3905 from 3917 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 781

Advancing to step 7:
781 goes into 128 0 times with a remainder of 128.
The next digit of our result is 0. 
Result so far: 12750.0
Subtract 0 from 128 to get 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 781

Going ahead to step 8:
781 goes into 1289 1 times with a remainder of 508.
Record the quotient 1 as the next digit in the result. 
Result so far: 127501.0
If we subtract 781 from 1289, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 9:
The number 781 fits into 5080 6 times, leaving a remainder of 394.
Record the quotient 6 as the next digit in the result. 
Result so far: 127501.6
Subtract 4686 from 5080 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 10:
The number 781 fits into 3940 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 127501.65
If we subtract 3905 from 3940, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
781 goes into 350 0 times with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 127501.65
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 12:
781 goes into 3500 4 times with a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 127501.6504
Deduct 3124 from 3500 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 13:
The number 781 fits into 3760 4 times, leaving a remainder of 636.
The next digit of our result is 4. 
Result so far: 127501.65044
Subtracting 3124 from 3760 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Our division results in 127501.65044 with a remaining 0.000636.
