15222731 ÷ 98 
We want to figure out the number of times 15222731 can be divided by 98.

On to step 1:
The number 98 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 98

Step 2:
98 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 98

Going ahead to step 3:
If we divide 152 by 98, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 98 from 152 and we're left with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 98

Step 4:
When dividing 542 by 98, we get 5 with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 490 from 542 and we're left with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 98

Advancing to step 5:
When dividing 522 by 98, we get 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Deduct 490 from 522 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 98

Advancing to step 6:
When dividing 327 by 98, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 1553.0
If we subtract 294 from 327, we get 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 98

On to step 7:
333 divided by 98 is 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 15533.0
Subtracting 294 from 333 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 98

Going ahead to step 8:
If we divide 391 by 98, we get 3 and a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 155333.0
If we subtract 294 from 391, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
If we divide 970 by 98, we get 9 and a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 155333.9
Subtract 882 from 970 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
If we divide 880 by 98, we get 8 and a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 155333.98
If we take 784 away from 880, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
960 divided by 98 is 9 with a remainder of 78.
The next digit of our result is 9. 
Result so far: 155333.989
The remainder is 78 after subtracting 882 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
If we divide 780 by 98, we get 7 and a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 155333.9897
Subtracting 686 from 780 leaves us 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.

On to step 13:
The number 98 fits into 940 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 155333.98979
Subtracting 882 from 940 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
98 can be fit into 580 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 155333.989795
Subtracting 490 from 580 leaves us 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 15:
98 can be fit into 900 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 155333.9897959
Subtract 882 from 900 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 16:
When dividing 180 by 98, we get 1 with a remainder of 82.
The next digit of our result is 1. 
Result so far: 155333.98979591
Subtracting 98 from 180 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

In conclusion, the division gives 155333.98979591 with a balance of 8.2e-08.
