We divide 8406397 by 99
Our goal is to divide 8406397 by 99.

On to step 1:
8 divided by 99 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 99

Let's proceed to step 2:
99 goes into 84 0 times with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 99

Going ahead to step 3:
The number 99 fits into 840 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 792 from 840 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 99

Going ahead to step 4:
The number 99 fits into 486 4 times, leaving a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 396 from 486 leaves us with 90.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 99

Step 5:
903 divided by 99 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 849.0
The remainder is 12 after subtracting 891 from 903.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 99

Moving on to step 6:
If we divide 129 by 99, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 8491.0
Subtract 99 from 129 to get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 99

Going ahead to step 7:
99 goes into 307 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 84913.0
Subtract 297 from 307 to 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 8:
99 goes into 100 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 84913.1
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
The number 99 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 84913.1
The remainder is 10 after subtracting 0 from 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 10:
99 goes into 100 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 84913.101
If we take 99 away from 100, we end up 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.

Going ahead to step 11:
When dividing 10 by 99, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 84913.101
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 99 fits into 100 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 84913.10101
If we take 99 away from 100, we end up 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.

Step 13:
The number 99 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 84913.10101
Subtract 0 from 10 to 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.

Let's proceed to step 14:
99 goes into 100 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 84913.1010101
If we take 99 away from 100, we end up 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.

On to step 15:
99 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 84913.1010101
Subtract 0 from 10 to 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.

Our division results in 84913.1010101 with a remaining 1e-08.
