We look at the division of 15402340 by 97 
We want to divide 15402340 by 97.

Moving on to step 1:
97 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 97

Step 2:
If we divide 15 by 97, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 97

Advancing to step 3:
If we divide 154 by 97, we get 1 and a remainder of 57.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 57 after subtracting 97 from 154.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 97

Advancing to step 4:
The number 97 fits into 570 5 times, leaving a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 485 from 570 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 97

Advancing to step 5:
852 divided by 97 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtracting 776 from 852 leaves us with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 97

Advancing to step 6:
97 can be fit into 763 7 times, resulting in a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
If we subtract 679 from 763, we get 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 97

Let's proceed to step 7:
If we divide 844 by 97, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 15878.0
If we take 776 away from 844, we end up with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 97

Advancing to step 8:
If we divide 680 by 97, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 158787.0
Subtract 679 from 680 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 97 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 158787.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
97 goes into 100 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 158787.01
Subtracting 97 from 100 leaves us with 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 11:
When dividing 30 by 97, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 158787.01
The remainder is 30 after subtracting 0 from 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 12:
If we divide 300 by 97, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 158787.0103
Deduct 291 from 300 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
97 can be fit into 90 0 times, resulting in a remainder of 90.
The next digit of our result is 0. 
Result so far: 158787.0103
Subtracting 0 from 90 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.

On to step 14:
If we divide 900 by 97, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 158787.010309
Subtract 873 from 900 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 15:
97 can be fit into 270 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 158787.0103092
Subtract 194 from 270 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
When dividing 760 by 97, we get 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 158787.01030927
If we subtract 679 from 760, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 158787.01030927 with a remaining 8.1e-08.
