54738891 divided by 402 
We want to figure out the number of times 54738891 can be divided by 402.

Moving on to step 1:
402 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
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 402

On to step 2:
54 divided by 402 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 402

Step 3:
402 goes into 547 1 times with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 402 from 547 and we're left with 145.
Bring next digit (3) of the dividend behind the 145 and repeat the process: 1453 / 402

Step 4:
If we divide 1453 by 402, we get 3 and a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1206 away from 1453, we end up with 247.
Bring next digit (8) of the dividend behind the 247 and repeat the process: 2478 / 402

On to step 5:
The number 402 fits into 2478 6 times, leaving a remainder of 66.
The next digit of our result is 6. 
Result so far: 136.0
If we subtract 2412 from 2478, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 402

Advancing to step 6:
668 divided by 402 is 1 with a remainder of 266.
Put 1 as the next digit of the answer. 
Result so far: 1361.0
Deduct 402 from 668 and we're left with 266.
Take the next digit (9) from the dividend and append it to 266, then repeat: 2669 / 402

Step 7:
402 goes into 2669 6 times with a remainder of 257.
Record the quotient 6 as the next digit in the result. 
Result so far: 13616.0
If we subtract 2412 from 2669, we get 257.
Fetch the next digit (1) from the dividend, attach it to 257 and continue: 2571 / 402

Going ahead to step 8:
When dividing 2571 by 402, we get 6 with a remainder of 159.
Use 6 as the next digit of our solution. 
Result so far: 136166.0
Subtract 2412 from 2571 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 9:
402 goes into 1590 3 times with a remainder of 384.
The number 3 becomes the next digit in our result. 
Result so far: 136166.3
Subtracting 1206 from 1590 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
If we divide 3840 by 402, we get 9 and a remainder of 222.
Use 9 as the next digit of our solution. 
Result so far: 136166.39
If we take 3618 away from 3840, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 11:
402 can be fit into 2220 5 times, resulting in a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 136166.395
If we subtract 2010 from 2220, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 12:
402 can be fit into 2100 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 136166.3955
Subtract 2010 from 2100 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 136166.3955 with a remaining 0.0009.
