We look at the division of 15617986 by 425 
Let's see how many times 425 fits into 15617986.

On to step 1:
425 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 425

Advancing to step 2:
When dividing 15 by 425, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
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 / 425

On to step 3:
When dividing 156 by 425, we get 0 with a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 156 to get 156.
Take the next digit (1) from the dividend and append it to 156, then repeat: 1561 / 425

Let's proceed to step 4:
The number 425 fits into 1561 3 times, leaving a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1275 from 1561 to get 286.
Include the next digit (7) from the dividend after 286, then repeat: 2867 / 425

Step 5:
When dividing 2867 by 425, we get 6 with a remainder of 317.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 2550 away from 2867, we end up with 317.
Append the next digit (9) from the dividend to 317 and continue with: 3179 / 425

Advancing to step 6:
If we divide 3179 by 425, we get 7 and a remainder of 204.
Use 7 as the next digit of our solution. 
Result so far: 367.0
Subtract 2975 from 3179 to get 204.
Include the next digit (8) from the dividend after 204, then repeat: 2048 / 425

On to step 7:
425 goes into 2048 4 times with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 3674.0
The remainder is 348 after subtracting 1700 from 2048.
Take the next digit (6) from the dividend and append it to 348, then repeat: 3486 / 425

On to step 8:
3486 divided by 425 is 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 36748.0
If we take 3400 away from 3486, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
860 divided by 425 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 36748.2
Deduct 850 from 860 and we're left 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.

Moving on to step 10:
When dividing 100 by 425, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 36748.2
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 425 fits into 1000 2 times, leaving a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 36748.202
Subtract 850 from 1000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 12:
If we divide 1500 by 425, we get 3 and a remainder of 225.
Use 3 as the next digit of our solution. 
Result so far: 36748.2023
Deduct 1275 from 1500 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 13:
When dividing 2250 by 425, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 36748.20235
Subtract 2125 from 2250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 14:
425 can be fit into 1250 2 times, resulting in a remainder of 400.
The next digit of our result is 2. 
Result so far: 36748.202352
Subtract 850 from 1250 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
The number 425 fits into 4000 9 times, leaving a remainder of 175.
Record the quotient 9 as the next digit in the result. 
Result so far: 36748.2023529
If we take 3825 away from 4000, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 16:
When dividing 1750 by 425, we get 4 with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 36748.20235294
Deduct 1700 from 1750 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 36748.20235294, and the remainder is 5e-08.
