421934 ÷ 47 
We're looking to find how many times 47 goes into 421934.

Step 1:
When dividing 4 by 47, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 47

Going ahead to step 2:
If we divide 42 by 47, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 47

On to step 3:
421 divided by 47 is 8 with a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 45 after subtracting 376 from 421.
Bring next digit (9) of the dividend behind the 45 and repeat the process: 459 / 47

Advancing to step 4:
When dividing 459 by 47, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 89.0
If we take 423 away from 459, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 47

Going ahead to step 5:
47 goes into 363 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Deduct 329 from 363 and we're left with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 47

On to step 6:
47 goes into 344 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 8977.0
Subtract 329 from 344 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
150 divided by 47 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 8977.3
If we subtract 141 from 150, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
The number 47 fits into 90 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 8977.31
If we take 47 away from 90, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 47, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 8977.319
The remainder is 7 after subtracting 423 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
When dividing 70 by 47, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 8977.3191
Deduct 47 from 70 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
230 divided by 47 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 8977.31914
If we take 188 away from 230, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
47 goes into 420 8 times with a remainder of 44.
The next digit of our result is 8. 
Result so far: 8977.319148
Deduct 376 from 420 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
The number 47 fits into 440 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 8977.3191489
Deduct 423 from 440 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
The number 47 fits into 170 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 8977.31914893
The remainder is 29 after subtracting 141 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 8977.31914893, with a leftover of 2.9e-08.
