Let's divide 54724590 by 426
We want to figure out the number of times 54724590 can be divided by 426.

Step 1:
426 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 426

Step 2:
426 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 426

Advancing to step 3:
426 goes into 547 1 times with a remainder of 121.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 426 from 547, we get 121.
Grab the next digit (2) from the dividend, add it to 121, then carry on: 1212 / 426

On to step 4:
1212 divided by 426 is 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 12.0
If we take 852 away from 1212, we end up with 360.
Include the next digit (4) from the dividend after 360, then repeat: 3604 / 426

Advancing to step 5:
The number 426 fits into 3604 8 times, leaving a remainder of 196.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 3408 from 3604, we get 196.
Grab the next digit (5) from the dividend, add it to 196, then carry on: 1965 / 426

Moving on to step 6:
426 goes into 1965 4 times with a remainder of 261.
Use 4 as the next digit of our solution. 
Result so far: 1284.0
If we take 1704 away from 1965, we end up with 261.
Grab the next digit (9) from the dividend, add it to 261, then carry on: 2619 / 426

Let's proceed to step 7:
426 can be fit into 2619 6 times, resulting in a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 12846.0
If we subtract 2556 from 2619, we get 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 426

Advancing to step 8:
If we divide 630 by 426, we get 1 and a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 128461.0
If we subtract 426 from 630, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 9:
426 goes into 2040 4 times with a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 128461.4
Deduct 1704 from 2040 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
The number 426 fits into 3360 7 times, leaving a remainder of 378.
The number 7 becomes the next digit in our result. 
Result so far: 128461.47
Deduct 2982 from 3360 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 11:
The number 426 fits into 3780 8 times, leaving a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 128461.478
If we take 3408 away from 3780, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 12:
If we divide 3720 by 426, we get 8 and a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 128461.4788
Subtract 3408 from 3720 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 128461.4788 with a remainder of 0.00312.
