78258584 ÷ 955 
We want to figure out the number of times 78258584 can be divided by 955.

On to step 1:
When dividing 7 by 955, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 955

Step 2:
955 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 955

Step 3:
If we divide 782 by 955, we get 0 and a remainder of 782.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 782 to get 782.
Include the next digit (5) from the dividend after 782, then repeat: 7825 / 955

Step 4:
When dividing 7825 by 955, we get 8 with a remainder of 185.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 185 after subtracting 7640 from 7825.
Bring next digit (8) of the dividend behind the 185 and repeat the process: 1858 / 955

Advancing to step 5:
1858 divided by 955 is 1 with a remainder of 903.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 955 from 1858 and we're left with 903.
Include the next digit (5) from the dividend after 903, then repeat: 9035 / 955

Let's proceed to step 6:
The number 955 fits into 9035 9 times, leaving a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 819.0
Subtracting 8595 from 9035 leaves us with 440.
Append the next digit (8) from the dividend to 440 and continue with: 4408 / 955

Going ahead to step 7:
955 can be fit into 4408 4 times, resulting in a remainder of 588.
Record the quotient 4 as the next digit in the result. 
Result so far: 8194.0
Subtracting 3820 from 4408 leaves us with 588.
Grab the next digit (4) from the dividend, add it to 588, then carry on: 5884 / 955

Let's proceed to step 8:
If we divide 5884 by 955, we get 6 and a remainder of 154.
The next digit of our result is 6. 
Result so far: 81946.0
If we take 5730 away from 5884, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 9:
If we divide 1540 by 955, we get 1 and a remainder of 585.
Use 1 as the next digit of our solution. 
Result so far: 81946.1
If we subtract 955 from 1540, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

On to step 10:
If we divide 5850 by 955, we get 6 and a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 81946.16
The remainder is 120 after subtracting 5730 from 5850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
955 goes into 1200 1 times with a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 81946.161
If we take 955 away from 1200, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 12:
The number 955 fits into 2450 2 times, leaving a remainder of 540.
Write down 2 as next digit of the result. 
Result so far: 81946.1612
The remainder is 540 after subtracting 1910 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 13:
The number 955 fits into 5400 5 times, leaving a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 81946.16125
If we take 4775 away from 5400, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Step 14:
The number 955 fits into 6250 6 times, leaving a remainder of 520.
The next digit of our result is 6. 
Result so far: 81946.161256
If we subtract 5730 from 6250, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
5200 divided by 955 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 81946.1612565
The remainder is 425 after subtracting 4775 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 16:
955 goes into 4250 4 times with a remainder of 430.
Put 4 as the next digit of the answer. 
Result so far: 81946.16125654
Deduct 3820 from 4250 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

In conclusion, the division gives 81946.16125654 with a balance of 4.3e-07.
