7171206 ÷ 421 
We want to divide 7171206 by 421.

Moving on to step 1:
421 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 421

Let's proceed to step 2:
71 divided by 421 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 421

Moving on to step 3:
421 goes into 717 1 times with a remainder of 296.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 421 away from 717, we end up with 296.
Include the next digit (1) from the dividend after 296, then repeat: 2961 / 421

Going ahead to step 4:
421 can be fit into 2961 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 2947 from 2961 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 421

Advancing to step 5:
421 goes into 142 0 times with a remainder of 142.
The next digit of our result is 0. 
Result so far: 170.0
If we take 0 away from 142, we end up with 142.
Take the next digit (0) from the dividend and append it to 142, then repeat: 1420 / 421

Let's proceed to step 6:
421 goes into 1420 3 times with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 1703.0
Subtracting 1263 from 1420 leaves us with 157.
Include the next digit (6) from the dividend after 157, then repeat: 1576 / 421

Let's proceed to step 7:
1576 divided by 421 is 3 with a remainder of 313.
The number 3 becomes the next digit in our result. 
Result so far: 17033.0
Deduct 1263 from 1576 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 8:
421 can be fit into 3130 7 times, resulting in a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 17033.7
Subtract 2947 from 3130 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 9:
1830 divided by 421 is 4 with a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 17033.74
The remainder is 146 after subtracting 1684 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 10:
If we divide 1460 by 421, we get 3 and a remainder of 197.
The next digit of our result is 3. 
Result so far: 17033.743
Subtract 1263 from 1460 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Step 11:
When dividing 1970 by 421, we get 4 with a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 17033.7434
If we take 1684 away from 1970, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 12:
421 can be fit into 2860 6 times, resulting in a remainder of 334.
Write down 6 as next digit of the result. 
Result so far: 17033.74346
If we subtract 2526 from 2860, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 13:
3340 divided by 421 is 7 with a remainder of 393.
Write down 7 as next digit of the result. 
Result so far: 17033.743467
If we subtract 2947 from 3340, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 14:
The number 421 fits into 3930 9 times, leaving a remainder of 141.
Write down 9 as next digit of the result. 
Result so far: 17033.7434679
If we subtract 3789 from 3930, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 15:
421 can be fit into 1410 3 times, resulting in a remainder of 147.
Use 3 as the next digit of our solution. 
Result so far: 17033.74346793
Subtracting 1263 from 1410 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The final outcome is 17033.74346793, with a leftover of 1.47e-07.
