17871388 divided by 125 
Our goal is to divide 17871388 by 125.

On to step 1:
1 divided by 125 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 125

On to step 2:
125 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 125

Moving on to step 3:
178 divided by 125 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 125 from 178 and we're left with 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 125

Step 4:
125 goes into 537 4 times with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 500 from 537 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 125

Let's proceed to step 5:
If we divide 371 by 125, we get 2 and a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Deduct 250 from 371 and we're left with 121.
Bring next digit (3) of the dividend behind the 121 and repeat the process: 1213 / 125

On to step 6:
The number 125 fits into 1213 9 times, leaving a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 1429.0
Subtract 1125 from 1213 to get 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 125

On to step 7:
The number 125 fits into 888 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 14297.0
Subtract 875 from 888 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 125

Advancing to step 8:
When dividing 138 by 125, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 142971.0
The remainder is 13 after subtracting 125 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
When dividing 130 by 125, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 142971.1
Subtracting 125 from 130 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
125 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 142971.1
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 125 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 142971.104
Subtracting 500 from 500 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
125 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 142971.104
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
0 divided by 125 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 142971.104
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 142971.104 with a remaining 0.0.
