We're dividing 99137980 by 479 
Our goal is to divide 99137980 by 479.

Let's proceed to step 1:
When dividing 9 by 479, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 479

Going ahead to step 2:
479 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 479

Advancing to step 3:
When dividing 991 by 479, we get 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 33 after subtracting 958 from 991.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 479

Let's proceed to step 4:
479 goes into 333 0 times with a remainder of 333.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 333 to get 333.
Grab the next digit (7) from the dividend, add it to 333, then carry on: 3337 / 479

Advancing to step 5:
The number 479 fits into 3337 6 times, leaving a remainder of 463.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtracting 2874 from 3337 leaves us with 463.
Append the next digit (9) from the dividend to 463 and continue with: 4639 / 479

Step 6:
When dividing 4639 by 479, we get 9 with a remainder of 328.
Use 9 as the next digit of our solution. 
Result so far: 2069.0
Subtract 4311 from 4639 to get 328.
Grab the next digit (8) from the dividend, add it to 328, then carry on: 3288 / 479

Step 7:
If we divide 3288 by 479, we get 6 and a remainder of 414.
The next digit of our result is 6. 
Result so far: 20696.0
Subtracting 2874 from 3288 leaves us with 414.
Take the next digit (0) from the dividend and append it to 414, then repeat: 4140 / 479

On to step 8:
4140 divided by 479 is 8 with a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 206968.0
Subtracting 3832 from 4140 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
The number 479 fits into 3080 6 times, leaving a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 206968.6
Subtracting 2874 from 3080 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 10:
479 can be fit into 2060 4 times, resulting in a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 206968.64
If we subtract 1916 from 2060, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
The number 479 fits into 1440 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 206968.643
Subtract 1437 from 1440 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
If we divide 30 by 479, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 206968.643
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
When dividing 300 by 479, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 206968.643
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 206968.643 with a remainder of 0.0003.
