We look at the division of 21350609 by 348 
We want to divide 21350609 by 348.

Moving on to step 1:
2 divided by 348 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 348

On to step 2:
348 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 348

On to step 3:
348 goes into 213 0 times with a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Include the next digit (5) from the dividend after 213, then repeat: 2135 / 348

Going ahead to step 4:
When dividing 2135 by 348, we get 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 2088 from 2135 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 348

Moving on to step 5:
470 divided by 348 is 1 with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 348 from 470 leaves us with 122.
Include the next digit (6) from the dividend after 122, then repeat: 1226 / 348

On to step 6:
1226 divided by 348 is 3 with a remainder of 182.
Put 3 as the next digit of the answer. 
Result so far: 613.0
If we subtract 1044 from 1226, we get 182.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 348

Let's proceed to step 7:
When dividing 1820 by 348, we get 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 6135.0
If we take 1740 away from 1820, we end up with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 348

Going ahead to step 8:
809 divided by 348 is 2 with a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 61352.0
Subtract 696 from 809 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
1130 divided by 348 is 3 with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 61352.3
If we take 1044 away from 1130, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 10:
348 goes into 860 2 times with a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 61352.32
Deduct 696 from 860 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
348 goes into 1640 4 times with a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 61352.324
If we subtract 1392 from 1640, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
348 goes into 2480 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 61352.3247
If we take 2436 away from 2480, we end up 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.

Advancing to step 13:
440 divided by 348 is 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 61352.32471
Subtract 348 from 440 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 14:
920 divided by 348 is 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 61352.324712
Deduct 696 from 920 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 15:
2240 divided by 348 is 6 with a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 61352.3247126
If we subtract 2088 from 2240, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 16:
The number 348 fits into 1520 4 times, leaving a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 61352.32471264
If we take 1392 away from 1520, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 61352.32471264, with a leftover of 1.28e-07.
