Let's divide 21054620 by 548
Let's see how many times 548 fits into 21054620.

Going ahead to step 1:
548 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 548

Moving on to step 2:
The number 548 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 548

Let's proceed to step 3:
548 can be fit into 210 0 times, resulting in a remainder of 210.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 548

Advancing to step 4:
548 goes into 2105 3 times with a remainder of 461.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1644 away from 2105, we end up with 461.
Include the next digit (4) from the dividend after 461, then repeat: 4614 / 548

Advancing to step 5:
548 can be fit into 4614 8 times, resulting in a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 4384 from 4614 leaves us with 230.
Take the next digit (6) from the dividend and append it to 230, then repeat: 2306 / 548

Advancing to step 6:
If we divide 2306 by 548, we get 4 and a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 384.0
Deduct 2192 from 2306 and we're left with 114.
Take the next digit (2) from the dividend and append it to 114, then repeat: 1142 / 548

On to step 7:
1142 divided by 548 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 3842.0
If we subtract 1096 from 1142, we get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 548

Let's proceed to step 8:
460 divided by 548 is 0 with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 38420.0
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 9:
When dividing 4600 by 548, we get 8 with a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 38420.8
Subtract 4384 from 4600 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 10:
548 goes into 2160 3 times with a remainder of 516.
Put 3 as the next digit of the answer. 
Result so far: 38420.83
The remainder is 516 after subtracting 1644 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 11:
5160 divided by 548 is 9 with a remainder of 228.
Put 9 as the next digit of the answer. 
Result so far: 38420.839
Subtracting 4932 from 5160 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
If we divide 2280 by 548, we get 4 and a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 38420.8394
Deduct 2192 from 2280 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
When dividing 880 by 548, we get 1 with a remainder of 332.
Put 1 as the next digit of the answer. 
Result so far: 38420.83941
Deduct 548 from 880 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 14:
548 goes into 3320 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 38420.839416
If we take 3288 away from 3320, we end up 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.

On to step 15:
548 goes into 320 0 times with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 38420.839416
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 16:
3200 divided by 548 is 5 with a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 38420.83941605
The remainder is 460 after subtracting 2740 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final outcome is 38420.83941605, with a leftover of 4.6e-07.
