61072090 ÷ 548 
We want to figure out the number of times 61072090 can be divided by 548.

Moving on to step 1:
The number 548 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 548

On to step 2:
The number 548 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 548

On to step 3:
The number 548 fits into 610 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 548 from 610 leaves us with 62.
Grab the next digit (7) from the dividend, add it to 62, then carry on: 627 / 548

Let's proceed to step 4:
If we divide 627 by 548, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 548 from 627 and we're left with 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 548

Step 5:
The number 548 fits into 792 1 times, leaving a remainder of 244.
The next digit of our result is 1. 
Result so far: 111.0
If we subtract 548 from 792, we get 244.
Bring next digit (0) of the dividend behind the 244 and repeat the process: 2440 / 548

Moving on to step 6:
2440 divided by 548 is 4 with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 1114.0
The remainder is 248 after subtracting 2192 from 2440.
Bring next digit (9) of the dividend behind the 248 and repeat the process: 2489 / 548

Let's proceed to step 7:
If we divide 2489 by 548, we get 4 and a remainder of 297.
The number 4 becomes the next digit in our result. 
Result so far: 11144.0
Deduct 2192 from 2489 and we're left with 297.
Take the next digit (0) from the dividend and append it to 297, then repeat: 2970 / 548

On to step 8:
2970 divided by 548 is 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 111445.0
If we subtract 2740 from 2970, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 9:
548 can be fit into 2300 4 times, resulting in a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 111445.4
Subtract 2192 from 2300 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
548 goes into 1080 1 times with a remainder of 532.
Put 1 as the next digit of the answer. 
Result so far: 111445.41
The remainder is 532 after subtracting 548 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 11:
The number 548 fits into 5320 9 times, leaving a remainder of 388.
The number 9 becomes the next digit in our result. 
Result so far: 111445.419
Subtracting 4932 from 5320 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 12:
If we divide 3880 by 548, we get 7 and a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 111445.4197
Subtract 3836 from 3880 to get 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:
440 divided by 548 is 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 111445.4197
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
When dividing 4400 by 548, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 111445.419708
Deduct 4384 from 4400 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
548 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 111445.419708
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
The number 548 fits into 1600 2 times, leaving a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 111445.41970802
Subtracting 1096 from 1600 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The final result is 111445.41970802 with a remainder of 5.04e-07.
