54085786 ÷ 674 
Our goal is to divide 54085786 by 674.

Going ahead to step 1:
674 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 674

Let's proceed to step 2:
The number 674 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 674

Let's proceed to step 3:
When dividing 540 by 674, we get 0 with a remainder of 540.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 540, we get 540.
Include the next digit (8) from the dividend after 540, then repeat: 5408 / 674

Let's proceed to step 4:
674 can be fit into 5408 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5392 away from 5408, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 674

On to step 5:
The number 674 fits into 165 0 times, leaving a remainder of 165.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 165 to get 165.
Fetch the next digit (7) from the dividend, attach it to 165 and continue: 1657 / 674

Let's proceed to step 6:
1657 divided by 674 is 2 with a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 802.0
Subtracting 1348 from 1657 leaves us with 309.
Bring next digit (8) of the dividend behind the 309 and repeat the process: 3098 / 674

Moving on to step 7:
3098 divided by 674 is 4 with a remainder of 402.
The next digit of our result is 4. 
Result so far: 8024.0
If we take 2696 away from 3098, we end up with 402.
Fetch the next digit (6) from the dividend, attach it to 402 and continue: 4026 / 674

Moving on to step 8:
674 can be fit into 4026 5 times, resulting in a remainder of 656.
Record the quotient 5 as the next digit in the result. 
Result so far: 80245.0
Deduct 3370 from 4026 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.

Let's proceed to step 9:
6560 divided by 674 is 9 with a remainder of 494.
Record the quotient 9 as the next digit in the result. 
Result so far: 80245.9
The remainder is 494 after subtracting 6066 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 10:
674 goes into 4940 7 times with a remainder of 222.
Write down 7 as next digit of the result. 
Result so far: 80245.97
If we subtract 4718 from 4940, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
When dividing 2220 by 674, we get 3 with a remainder of 198.
Record the quotient 3 as the next digit in the result. 
Result so far: 80245.973
Subtracting 2022 from 2220 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 12:
674 goes into 1980 2 times with a remainder of 632.
Use 2 as the next digit of our solution. 
Result so far: 80245.9732
Subtract 1348 from 1980 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 13:
674 goes into 6320 9 times with a remainder of 254.
Write down 9 as next digit of the result. 
Result so far: 80245.97329
If we take 6066 away from 6320, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 14:
2540 divided by 674 is 3 with a remainder of 518.
The next digit of our result is 3. 
Result so far: 80245.973293
Subtracting 2022 from 2540 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 15:
674 goes into 5180 7 times with a remainder of 462.
The number 7 becomes the next digit in our result. 
Result so far: 80245.9732937
Deduct 4718 from 5180 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 16:
674 goes into 4620 6 times with a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 80245.97329376
Deduct 4044 from 4620 and we're left with 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 final outcome is 80245.97329376, with a leftover of 5.76e-07.
