8391778 ÷ 93 
We want to figure out the number of times 8391778 can be divided by 93.

Step 1:
93 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 93

On to step 2:
If we divide 83 by 93, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 93

On to step 3:
93 goes into 839 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 837 from 839 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 93

Let's proceed to step 4:
When dividing 21 by 93, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 21, we end up with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 93

Moving on to step 5:
If we divide 217 by 93, we get 2 and a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 902.0
If we take 186 away from 217, we end up with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 93

Advancing to step 6:
317 divided by 93 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 9023.0
If we take 279 away from 317, we end up with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 93

Advancing to step 7:
If we divide 388 by 93, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 90234.0
If we subtract 372 from 388, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
If we divide 160 by 93, we get 1 and a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 90234.1
The remainder is 67 after subtracting 93 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
The number 93 fits into 670 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 90234.17
If we subtract 651 from 670, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
If we divide 190 by 93, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 90234.172
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 93, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 90234.172
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
When dividing 400 by 93, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 90234.17204
Deduct 372 from 400 and we're left 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.

Moving on to step 13:
When dividing 280 by 93, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 90234.172043
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
The number 93 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 90234.172043
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
When dividing 100 by 93, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 90234.17204301
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 90234.17204301 with a remaining 7e-09.
