Let's divide 54198121 by 904
Our goal is to divide 54198121 by 904.

Going ahead to step 1:
5 divided by 904 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 904

Step 2:
If we divide 54 by 904, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 904

Going ahead to step 3:
541 divided by 904 is 0 with a remainder of 541.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 541, we end up with 541.
Take the next digit (9) from the dividend and append it to 541, then repeat: 5419 / 904

Moving on to step 4:
When dividing 5419 by 904, we get 5 with a remainder of 899.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 4520 from 5419 leaves us with 899.
Grab the next digit (8) from the dividend, add it to 899, then carry on: 8998 / 904

Step 5:
If we divide 8998 by 904, we get 9 and a remainder of 862.
Write down 9 as next digit of the result. 
Result so far: 59.0
Deduct 8136 from 8998 and we're left with 862.
Bring next digit (1) of the dividend behind the 862 and repeat the process: 8621 / 904

Advancing to step 6:
The number 904 fits into 8621 9 times, leaving a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 599.0
If we subtract 8136 from 8621, we get 485.
Take the next digit (2) from the dividend and append it to 485, then repeat: 4852 / 904

On to step 7:
The number 904 fits into 4852 5 times, leaving a remainder of 332.
The number 5 becomes the next digit in our result. 
Result so far: 5995.0
The remainder is 332 after subtracting 4520 from 4852.
Append the next digit (1) from the dividend to 332 and continue with: 3321 / 904

Going ahead to step 8:
904 can be fit into 3321 3 times, resulting in a remainder of 609.
The number 3 becomes the next digit in our result. 
Result so far: 59953.0
The remainder is 609 after subtracting 2712 from 3321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 9:
904 goes into 6090 6 times with a remainder of 666.
Record the quotient 6 as the next digit in the result. 
Result so far: 59953.6
Subtract 5424 from 6090 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 10:
The number 904 fits into 6660 7 times, leaving a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 59953.67
If we take 6328 away from 6660, we end up 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 11:
904 can be fit into 3320 3 times, resulting in a remainder of 608.
Use 3 as the next digit of our solution. 
Result so far: 59953.673
Subtract 2712 from 3320 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 12:
904 can be fit into 6080 6 times, resulting in a remainder of 656.
Record the quotient 6 as the next digit in the result. 
Result so far: 59953.6736
Deduct 5424 from 6080 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 13:
When dividing 6560 by 904, we get 7 with a remainder of 232.
The number 7 becomes the next digit in our result. 
Result so far: 59953.67367
Subtract 6328 from 6560 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 14:
904 goes into 2320 2 times with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 59953.673672
Deduct 1808 from 2320 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 15:
The number 904 fits into 5120 5 times, leaving a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 59953.6736725
Deduct 4520 from 5120 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 16:
6000 divided by 904 is 6 with a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 59953.67367256
Subtract 5424 from 6000 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 59953.67367256, and the remainder is 5.76e-07.
