15639097 ÷ 158 
Let's see how many times 158 fits into 15639097.

Let's proceed to step 1:
When dividing 1 by 158, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 158

Let's proceed to step 2:
15 divided by 158 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 158

On to step 3:
If we divide 156 by 158, we get 0 and a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Fetch the next digit (3) from the dividend, attach it to 156 and continue: 1563 / 158

Moving on to step 4:
When dividing 1563 by 158, we get 9 with a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 1422 from 1563, we get 141.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 158

Advancing to step 5:
If we divide 1419 by 158, we get 8 and a remainder of 155.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 1264 from 1419, we get 155.
Take the next digit (0) from the dividend and append it to 155, then repeat: 1550 / 158

Moving on to step 6:
The number 158 fits into 1550 9 times, leaving a remainder of 128.
Write down 9 as next digit of the result. 
Result so far: 989.0
If we take 1422 away from 1550, we end up with 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 158

Moving on to step 7:
When dividing 1289 by 158, we get 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 9898.0
Deduct 1264 from 1289 and we're left with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 158

On to step 8:
158 goes into 257 1 times with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 98981.0
Subtracting 158 from 257 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
The number 158 fits into 990 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 98981.6
Subtract 948 from 990 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
158 can be fit into 420 2 times, resulting in a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 98981.62
Deduct 316 from 420 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
158 goes into 1040 6 times with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 98981.626
Subtract 948 from 1040 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 12:
158 can be fit into 920 5 times, resulting in a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 98981.6265
Deduct 790 from 920 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
158 can be fit into 1300 8 times, resulting in a remainder of 36.
The next digit of our result is 8. 
Result so far: 98981.62658
Deduct 1264 from 1300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
158 goes into 360 2 times with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 98981.626582
If we take 316 away from 360, we end up 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.

Let's proceed to step 15:
When dividing 440 by 158, we get 2 with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 98981.6265822
Subtracting 316 from 440 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

In conclusion, the division gives 98981.6265822 with a balance of 1.24e-06.
