We're dividing 21115209 by 980 
We're looking to find how many times 980 goes into 21115209.

Step 1:
If we divide 2 by 980, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 980

Step 2:
980 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 980

Advancing to step 3:
The number 980 fits into 211 0 times, leaving a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 211 and we're left with 211.
Fetch the next digit (1) from the dividend, attach it to 211 and continue: 2111 / 980

Advancing to step 4:
The number 980 fits into 2111 2 times, leaving a remainder of 151.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1960 from 2111 leaves us with 151.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 980

Let's proceed to step 5:
980 can be fit into 1515 1 times, resulting in a remainder of 535.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 980 from 1515, we get 535.
Include the next digit (2) from the dividend after 535, then repeat: 5352 / 980

Going ahead to step 6:
5352 divided by 980 is 5 with a remainder of 452.
The next digit of our result is 5. 
Result so far: 215.0
Subtract 4900 from 5352 to get 452.
Grab the next digit (0) from the dividend, add it to 452, then carry on: 4520 / 980

Going ahead to step 7:
980 goes into 4520 4 times with a remainder of 600.
Use 4 as the next digit of our solution. 
Result so far: 2154.0
Subtracting 3920 from 4520 leaves us with 600.
Fetch the next digit (9) from the dividend, attach it to 600 and continue: 6009 / 980

Let's proceed to step 8:
980 goes into 6009 6 times with a remainder of 129.
Record the quotient 6 as the next digit in the result. 
Result so far: 21546.0
Subtracting 5880 from 6009 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 9:
The number 980 fits into 1290 1 times, leaving a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 21546.1
Subtracting 980 from 1290 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
980 can be fit into 3100 3 times, resulting in a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 21546.13
The remainder is 160 after subtracting 2940 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
When dividing 1600 by 980, we get 1 with a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 21546.131
Deduct 980 from 1600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 12:
6200 divided by 980 is 6 with a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 21546.1316
Subtracting 5880 from 6200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
980 goes into 3200 3 times with a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 21546.13163
If we take 2940 away from 3200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 14:
The number 980 fits into 2600 2 times, leaving a remainder of 640.
The number 2 becomes the next digit in our result. 
Result so far: 21546.131632
Subtracting 1960 from 2600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 15:
When dividing 6400 by 980, we get 6 with a remainder of 520.
The next digit of our result is 6. 
Result so far: 21546.1316326
If we take 5880 away from 6400, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 16:
If we divide 5200 by 980, we get 5 and a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 21546.13163265
If we take 4900 away from 5200, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 21546.13163265 and a remainder of 3e-07.
