We divide 79669939 by 918
We want to figure out the number of times 79669939 can be divided by 918.

On to step 1:
918 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 918

Step 2:
918 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 918

Moving on to step 3:
If we divide 796 by 918, we get 0 and a remainder of 796.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 796, we end up with 796.
Append the next digit (6) from the dividend to 796 and continue with: 7966 / 918

Going ahead to step 4:
918 can be fit into 7966 8 times, resulting in a remainder of 622.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7344 from 7966 to get 622.
Include the next digit (9) from the dividend after 622, then repeat: 6229 / 918

Step 5:
918 goes into 6229 6 times with a remainder of 721.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 5508 from 6229 to get 721.
Grab the next digit (9) from the dividend, add it to 721, then carry on: 7219 / 918

On to step 6:
918 can be fit into 7219 7 times, resulting in a remainder of 793.
Write down 7 as next digit of the result. 
Result so far: 867.0
Deduct 6426 from 7219 and we're left with 793.
Append the next digit (3) from the dividend to 793 and continue with: 7933 / 918

On to step 7:
If we divide 7933 by 918, we get 8 and a remainder of 589.
Use 8 as the next digit of our solution. 
Result so far: 8678.0
Deduct 7344 from 7933 and we're left with 589.
Grab the next digit (9) from the dividend, add it to 589, then carry on: 5899 / 918

Going ahead to step 8:
When dividing 5899 by 918, we get 6 with a remainder of 391.
Use 6 as the next digit of our solution. 
Result so far: 86786.0
If we take 5508 away from 5899, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 9:
918 can be fit into 3910 4 times, resulting in a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 86786.4
If we take 3672 away from 3910, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
If we divide 2380 by 918, we get 2 and a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 86786.42
If we subtract 1836 from 2380, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 11:
The number 918 fits into 5440 5 times, leaving a remainder of 850.
The number 5 becomes the next digit in our result. 
Result so far: 86786.425
Deduct 4590 from 5440 and we're left with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Going ahead to step 12:
The number 918 fits into 8500 9 times, leaving a remainder of 238.
The number 9 becomes the next digit in our result. 
Result so far: 86786.4259
Deduct 8262 from 8500 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 13:
When dividing 2380 by 918, we get 2 with a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 86786.42592
Deduct 1836 from 2380 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 14:
918 goes into 5440 5 times with a remainder of 850.
The next digit of our result is 5. 
Result so far: 86786.425925
The remainder is 850 after subtracting 4590 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Moving on to step 15:
When dividing 8500 by 918, we get 9 with a remainder of 238.
Put 9 as the next digit of the answer. 
Result so far: 86786.4259259
The remainder is 238 after subtracting 8262 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 16:
The number 918 fits into 2380 2 times, leaving a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 86786.42592592
Subtracting 1836 from 2380 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final result is 86786.42592592 with a remainder of 5.44e-07.
