We're dividing 18478993 by 107 
We want to figure out the number of times 18478993 can be divided by 107.

Let's proceed to step 1:
The number 107 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 107

Moving on to step 2:
If we divide 18 by 107, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 107

Advancing to step 3:
When dividing 184 by 107, we get 1 with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 107 from 184, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 107

Step 4:
The number 107 fits into 777 7 times, leaving a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 749 from 777 leaves us with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 107

On to step 5:
When dividing 288 by 107, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 172.0
Subtracting 214 from 288 leaves us with 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 107

On to step 6:
If we divide 749 by 107, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1727.0
If we take 749 away from 749, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 107

Step 7:
107 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 17270.0
Subtract 0 from 9 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 107

On to step 8:
The number 107 fits into 93 0 times, leaving a remainder of 93.
The next digit of our result is 0. 
Result so far: 172700.0
The remainder is 93 after subtracting 0 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 9:
107 can be fit into 930 8 times, resulting in a remainder of 74.
The next digit of our result is 8. 
Result so far: 172700.8
Deduct 856 from 930 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
The number 107 fits into 740 6 times, leaving a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 172700.86
Deduct 642 from 740 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 11:
If we divide 980 by 107, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 172700.869
If we take 963 away from 980, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
170 divided by 107 is 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 172700.8691
Subtract 107 from 170 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
107 goes into 630 5 times with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 172700.86915
If we subtract 535 from 630, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 14:
107 can be fit into 950 8 times, resulting in a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 172700.869158
Deduct 856 from 950 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 15:
107 can be fit into 940 8 times, resulting in a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 172700.8691588
The remainder is 84 after subtracting 856 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 172700.8691588 with a remainder of 8.4e-07.
