54040093 ÷ 149 
Our goal is to divide 54040093 by 149.

Step 1:
When dividing 5 by 149, we get 0 with 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 / 149

Advancing to step 2:
If we divide 54 by 149, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 149

Let's proceed to step 3:
149 goes into 540 3 times with a remainder of 93.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 93 after subtracting 447 from 540.
Fetch the next digit (4) from the dividend, attach it to 93 and continue: 934 / 149

Step 4:
When dividing 934 by 149, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 894 from 934, we get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 149

Going ahead to step 5:
149 can be fit into 400 2 times, resulting in a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Subtract 298 from 400 to get 102.
Fetch the next digit (0) from the dividend, attach it to 102 and continue: 1020 / 149

Going ahead to step 6:
The number 149 fits into 1020 6 times, leaving a remainder of 126.
The next digit of our result is 6. 
Result so far: 3626.0
If we subtract 894 from 1020, we get 126.
Take the next digit (9) from the dividend and append it to 126, then repeat: 1269 / 149

Advancing to step 7:
149 can be fit into 1269 8 times, resulting in a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 36268.0
Subtract 1192 from 1269 to get 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 149

Step 8:
If we divide 773 by 149, we get 5 and a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 362685.0
Deduct 745 from 773 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 149, we get 1 and a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 362685.1
Subtract 149 from 280 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 10:
When dividing 1310 by 149, we get 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 362685.18
Deduct 1192 from 1310 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 11:
149 goes into 1180 7 times with a remainder of 137.
The next digit of our result is 7. 
Result so far: 362685.187
If we subtract 1043 from 1180, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 12:
149 can be fit into 1370 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 362685.1879
The remainder is 29 after subtracting 1341 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
149 can be fit into 290 1 times, resulting in a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 362685.18791
The remainder is 141 after subtracting 149 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 14:
1410 divided by 149 is 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 362685.187919
Subtracting 1341 from 1410 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 15:
When dividing 690 by 149, we get 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 362685.1879194
The remainder is 94 after subtracting 596 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 16:
When dividing 940 by 149, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 362685.18791946
If we subtract 894 from 940, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 362685.18791946 with a remaining 4.6e-08.
