Let's divide 7210135 by 171
We want to divide 7210135 by 171.

Let's proceed to step 1:
When dividing 7 by 171, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 171

On to step 2:
If we divide 72 by 171, we get 0 and a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 171

Let's proceed to step 3:
721 divided by 171 is 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 684 from 721 and we're left with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 171

Let's proceed to step 4:
If we divide 370 by 171, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 28 after subtracting 342 from 370.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 171

Going ahead to step 5:
The number 171 fits into 281 1 times, leaving a remainder of 110.
The next digit of our result is 1. 
Result so far: 421.0
The remainder is 110 after subtracting 171 from 281.
Take the next digit (3) from the dividend and append it to 110, then repeat: 1103 / 171

On to step 6:
171 can be fit into 1103 6 times, resulting in a remainder of 77.
The number 6 becomes the next digit in our result. 
Result so far: 4216.0
The remainder is 77 after subtracting 1026 from 1103.
Include the next digit (5) from the dividend after 77, then repeat: 775 / 171

Let's proceed to step 7:
The number 171 fits into 775 4 times, leaving a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 42164.0
Deduct 684 from 775 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 8:
171 can be fit into 910 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 42164.5
Subtract 855 from 910 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
550 divided by 171 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 42164.53
If we take 513 away from 550, we end up 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.

Going ahead to step 10:
If we divide 370 by 171, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 42164.532
The remainder is 28 after subtracting 342 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
171 goes into 280 1 times with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 42164.5321
If we take 171 away from 280, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 12:
1090 divided by 171 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 42164.53216
Subtracting 1026 from 1090 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
When dividing 640 by 171, we get 3 with a remainder of 127.
The next digit of our result is 3. 
Result so far: 42164.532163
If we subtract 513 from 640, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 14:
If we divide 1270 by 171, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 42164.5321637
If we take 1197 away from 1270, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 15:
171 goes into 730 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 42164.53216374
Subtract 684 from 730 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 42164.53216374, with a leftover of 4.6e-08.
