We're dividing 8458440 by 107 
We're looking to find how many times 107 goes into 8458440.

Step 1:
When dividing 8 by 107, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 107

On to step 2:
When dividing 84 by 107, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 107

Advancing to step 3:
When dividing 845 by 107, we get 7 with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 749 from 845 leaves us with 96.
Bring next digit (8) of the dividend behind the 96 and repeat the process: 968 / 107

Going ahead to step 4:
When dividing 968 by 107, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 963 from 968, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 107

Moving on to step 5:
If we divide 54 by 107, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 790.0
Subtract 0 from 54 to get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 107

Step 6:
107 can be fit into 544 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 7905.0
If we take 535 away from 544, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 107

Let's proceed to step 7:
If we divide 90 by 107, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 79050.0
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 8:
107 goes into 900 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 79050.8
Subtracting 856 from 900 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
The number 107 fits into 440 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 79050.84
Deduct 428 from 440 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
107 can be fit into 120 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 79050.841
Deduct 107 from 120 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
107 goes into 130 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 79050.8411
Deduct 107 from 130 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 79050.8411, and the remainder is 0.00023.
