45451140 ÷ 69 
Our goal is to divide 45451140 by 69.

Step 1:
When dividing 4 by 69, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 69

Moving on to step 2:
When dividing 45 by 69, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 69

Moving on to step 3:
If we divide 454 by 69, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 414 away from 454, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 69

On to step 4:
69 can be fit into 405 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Deduct 345 from 405 and we're left with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 69

Moving on to step 5:
69 goes into 601 8 times with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 658.0
If we subtract 552 from 601, we get 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 69

Moving on to step 6:
69 goes into 491 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 6587.0
The remainder is 8 after subtracting 483 from 491.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 69

Advancing to step 7:
The number 69 fits into 84 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 65871.0
The remainder is 15 after subtracting 69 from 84.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 69

Let's proceed to step 8:
69 can be fit into 150 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 658712.0
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 69 fits into 120 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 658712.1
Deduct 69 from 120 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
69 can be fit into 510 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 658712.17
Subtracting 483 from 510 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 69, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 658712.173
Deduct 207 from 270 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
69 goes into 630 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 658712.1739
The remainder is 9 after subtracting 621 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
69 can be fit into 90 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 658712.17391
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
The number 69 fits into 210 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 658712.173913
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
30 divided by 69 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 658712.173913
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 16:
300 divided by 69 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 658712.17391304
If we take 276 away from 300, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 658712.17391304, with a leftover of 2.4e-08.
