69986903 ÷ 54 
Let's see how many times 54 fits into 69986903.

Step 1:
The number 54 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 54

On to step 2:
54 goes into 69 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 54 away from 69, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 54

On to step 3:
54 can be fit into 159 2 times, resulting in a remainder of 51.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 108 from 159 leaves us with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 54

Advancing to step 4:
54 can be fit into 518 9 times, resulting in a remainder of 32.
The next digit of our result is 9. 
Result so far: 129.0
The remainder is 32 after subtracting 486 from 518.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 54

Advancing to step 5:
326 divided by 54 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 1296.0
Deduct 324 from 326 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 54

Moving on to step 6:
54 can be fit into 29 0 times, resulting in a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 12960.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 54

Going ahead to step 7:
54 goes into 290 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 129605.0
Subtracting 270 from 290 leaves us with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 54

Step 8:
When dividing 203 by 54, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 1296053.0
If we subtract 162 from 203, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
When dividing 410 by 54, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1296053.7
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
The number 54 fits into 320 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1296053.75
If we subtract 270 from 320, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
54 goes into 500 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 1296053.759
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
54 goes into 140 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1296053.7592
If we take 108 away from 140, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
When dividing 320 by 54, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1296053.75925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
If we divide 500 by 54, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 1296053.759259
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
54 can be fit into 140 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1296053.7592592
Subtract 108 from 140 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
54 can be fit into 320 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1296053.75925925
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 1296053.75925925 and a remainder of 5e-08.
