15810870 divided by 395 
Our goal is to divide 15810870 by 395.

On to step 1:
The number 395 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 395

Let's proceed to step 2:
When dividing 15 by 395, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 395

Let's proceed to step 3:
When dividing 158 by 395, we get 0 with a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 158 to get 158.
Append the next digit (1) from the dividend to 158 and continue with: 1581 / 395

Let's proceed to step 4:
395 can be fit into 1581 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1580 from 1581 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 395

Advancing to step 5:
10 divided by 395 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 10 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 395

Moving on to step 6:
The number 395 fits into 108 0 times, leaving a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 400.0
Subtracting 0 from 108 leaves us with 108.
Fetch the next digit (7) from the dividend, attach it to 108 and continue: 1087 / 395

Moving on to step 7:
The number 395 fits into 1087 2 times, leaving a remainder of 297.
The next digit of our result is 2. 
Result so far: 4002.0
Subtracting 790 from 1087 leaves us with 297.
Take the next digit (0) from the dividend and append it to 297, then repeat: 2970 / 395

Going ahead to step 8:
If we divide 2970 by 395, we get 7 and a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 40027.0
Subtract 2765 from 2970 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 9:
The number 395 fits into 2050 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 40027.5
The remainder is 75 after subtracting 1975 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
750 divided by 395 is 1 with a remainder of 355.
Use 1 as the next digit of our solution. 
Result so far: 40027.51
Deduct 395 from 750 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 11:
395 goes into 3550 8 times with a remainder of 390.
The next digit of our result is 8. 
Result so far: 40027.518
If we take 3160 away from 3550, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 12:
The number 395 fits into 3900 9 times, leaving a remainder of 345.
Use 9 as the next digit of our solution. 
Result so far: 40027.5189
Subtracting 3555 from 3900 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 13:
395 goes into 3450 8 times with a remainder of 290.
Record the quotient 8 as the next digit in the result. 
Result so far: 40027.51898
The remainder is 290 after subtracting 3160 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 14:
395 goes into 2900 7 times with a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 40027.518987
The remainder is 135 after subtracting 2765 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 15:
395 can be fit into 1350 3 times, resulting in a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 40027.5189873
If we take 1185 away from 1350, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 16:
If we divide 1650 by 395, we get 4 and a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 40027.51898734
Deduct 1580 from 1650 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 40027.51898734 and a remainder of 7e-08.
