We look at the division of 15871789 by 207 
We're looking to find how many times 207 goes into 15871789.

Going ahead to step 1:
207 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 207

Step 2:
The number 207 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 207

On to step 3:
When dividing 158 by 207, we get 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Append the next digit (7) from the dividend to 158 and continue with: 1587 / 207

Going ahead to step 4:
207 can be fit into 1587 7 times, resulting in a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 1449 from 1587, we get 138.
Append the next digit (1) from the dividend to 138 and continue with: 1381 / 207

On to step 5:
207 can be fit into 1381 6 times, resulting in a remainder of 139.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 1242 from 1381 to get 139.
Take the next digit (7) from the dividend and append it to 139, then repeat: 1397 / 207

Let's proceed to step 6:
When dividing 1397 by 207, we get 6 with a remainder of 155.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
The remainder is 155 after subtracting 1242 from 1397.
Include the next digit (8) from the dividend after 155, then repeat: 1558 / 207

Step 7:
207 can be fit into 1558 7 times, resulting in a remainder of 109.
Record the quotient 7 as the next digit in the result. 
Result so far: 7667.0
If we take 1449 away from 1558, we end up with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 207

Going ahead to step 8:
If we divide 1099 by 207, we get 5 and a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 76675.0
If we subtract 1035 from 1099, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 207 is 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 76675.3
If we subtract 621 from 640, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
If we divide 190 by 207, we get 0 and a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 76675.3
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
When dividing 1900 by 207, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 76675.309
Subtracting 1863 from 1900 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 207, we get 1 and a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 76675.3091
If we take 207 away from 370, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 13:
The number 207 fits into 1630 7 times, leaving a remainder of 181.
The next digit of our result is 7. 
Result so far: 76675.30917
Subtracting 1449 from 1630 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 14:
207 goes into 1810 8 times with a remainder of 154.
The next digit of our result is 8. 
Result so far: 76675.309178
Subtracting 1656 from 1810 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 15:
The number 207 fits into 1540 7 times, leaving a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 76675.3091787
The remainder is 91 after subtracting 1449 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 16:
When dividing 910 by 207, we get 4 with a remainder of 82.
The next digit of our result is 4. 
Result so far: 76675.30917874
Subtracting 828 from 910 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.

The quotient of the division is 76675.30917874, and the remainder is 8.2e-08.
