Let's divide 16927015 by 421
We want to figure out the number of times 16927015 can be divided by 421.

Moving on to step 1:
The number 421 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 421

Moving on to step 2:
16 divided by 421 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 421

Let's proceed to step 3:
When dividing 169 by 421, we get 0 with a remainder of 169.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 169 and we're left with 169.
Bring next digit (2) of the dividend behind the 169 and repeat the process: 1692 / 421

Advancing to step 4:
421 goes into 1692 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1684 from 1692 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 421

Let's proceed to step 5:
The number 421 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 421

Moving on to step 6:
421 goes into 870 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 402.0
The remainder is 28 after subtracting 842 from 870.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 421

Let's proceed to step 7:
281 divided by 421 is 0 with a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 4020.0
Deduct 0 from 281 and we're left with 281.
Fetch the next digit (5) from the dividend, attach it to 281 and continue: 2815 / 421

Moving on to step 8:
421 goes into 2815 6 times with a remainder of 289.
The number 6 becomes the next digit in our result. 
Result so far: 40206.0
If we take 2526 away from 2815, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
The number 421 fits into 2890 6 times, leaving a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 40206.6
If we subtract 2526 from 2890, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 10:
3640 divided by 421 is 8 with a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 40206.68
If we subtract 3368 from 3640, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
If we divide 2720 by 421, we get 6 and a remainder of 194.
The next digit of our result is 6. 
Result so far: 40206.686
If we subtract 2526 from 2720, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 12:
When dividing 1940 by 421, we get 4 with a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 40206.6864
If we take 1684 away from 1940, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
421 goes into 2560 6 times with a remainder of 34.
The next digit of our result is 6. 
Result so far: 40206.68646
If we subtract 2526 from 2560, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
340 divided by 421 is 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 40206.68646
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
When dividing 3400 by 421, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 40206.6864608
Deduct 3368 from 3400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
320 divided by 421 is 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 40206.6864608
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 40206.6864608, with a leftover of 3.2e-07.
