421564 ÷ 49 
Our goal is to divide 421564 by 49.

Moving on to step 1:
49 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 49

Going ahead to step 2:
When dividing 42 by 49, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 49

Going ahead to step 3:
When dividing 421 by 49, we get 8 with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 29 after subtracting 392 from 421.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 49

Let's proceed to step 4:
If we divide 295 by 49, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 1 after subtracting 294 from 295.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 49

Step 5:
16 divided by 49 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 860.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 49

Let's proceed to step 6:
164 divided by 49 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 8603.0
If we take 147 away from 164, we end up 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.

Moving on to step 7:
If we divide 170 by 49, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 8603.3
Deduct 147 from 170 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.

Step 8:
When dividing 230 by 49, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 8603.34
Subtracting 196 from 230 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 49 fits into 340 6 times, leaving a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 8603.346
Subtract 294 from 340 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.

Going ahead to step 10:
49 goes into 460 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 8603.3469
Subtract 441 from 460 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
The number 49 fits into 190 3 times, leaving a remainder of 43.
The next digit of our result is 3. 
Result so far: 8603.34693
Subtracting 147 from 190 leaves us 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.

Moving on to step 12:
The number 49 fits into 430 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 8603.346938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
49 can be fit into 380 7 times, resulting in a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 8603.3469387
The remainder is 37 after subtracting 343 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
370 divided by 49 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 8603.34693877
If we subtract 343 from 370, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 8603.34693877 with a remainder of 2.7e-08.
