We look at the division of 42820190 by 548 
We're looking to find how many times 548 goes into 42820190.

Let's proceed to step 1:
When dividing 4 by 548, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 548

Moving on to step 2:
548 can be fit into 42 0 times, resulting in 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.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 548

Step 3:
548 can be fit into 428 0 times, resulting in a remainder of 428.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Append the next digit (2) from the dividend to 428 and continue with: 4282 / 548

Let's proceed to step 4:
If we divide 4282 by 548, we get 7 and a remainder of 446.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 446 after subtracting 3836 from 4282.
Take the next digit (0) from the dividend and append it to 446, then repeat: 4460 / 548

Moving on to step 5:
548 can be fit into 4460 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 76 after subtracting 4384 from 4460.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 548

Going ahead to step 6:
When dividing 761 by 548, we get 1 with a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 781.0
The remainder is 213 after subtracting 548 from 761.
Bring next digit (9) of the dividend behind the 213 and repeat the process: 2139 / 548

Advancing to step 7:
548 can be fit into 2139 3 times, resulting in a remainder of 495.
Put 3 as the next digit of the answer. 
Result so far: 7813.0
If we subtract 1644 from 2139, we get 495.
Grab the next digit (0) from the dividend, add it to 495, then carry on: 4950 / 548

Step 8:
When dividing 4950 by 548, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 78139.0
If we subtract 4932 from 4950, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
548 can be fit into 180 0 times, resulting in a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 78139.0
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
When dividing 1800 by 548, we get 3 with a remainder of 156.
Record the quotient 3 as the next digit in the result. 
Result so far: 78139.03
Deduct 1644 from 1800 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
1560 divided by 548 is 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 78139.032
If we subtract 1096 from 1560, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 12:
548 can be fit into 4640 8 times, resulting in a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 78139.0328
Subtract 4384 from 4640 to get 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:
When dividing 2560 by 548, we get 4 with a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 78139.03284
Subtract 2192 from 2560 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 14:
548 can be fit into 3680 6 times, resulting in a remainder of 392.
The next digit of our result is 6. 
Result so far: 78139.032846
If we subtract 3288 from 3680, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 15:
The number 548 fits into 3920 7 times, leaving a remainder of 84.
The next digit of our result is 7. 
Result so far: 78139.0328467
The remainder is 84 after subtracting 3836 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 16:
840 divided by 548 is 1 with a remainder of 292.
The next digit of our result is 1. 
Result so far: 78139.03284671
Subtract 548 from 840 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

In conclusion, the division gives 78139.03284671 with a balance of 2.92e-07.
