We're dividing 58403654 by 777 
We're looking to find how many times 777 goes into 58403654.

Let's proceed to step 1:
The number 777 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 777

Advancing to step 2:
When dividing 58 by 777, we get 0 with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 777

Advancing to step 3:
584 divided by 777 is 0 with a remainder of 584.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 584, we end up with 584.
Include the next digit (0) from the dividend after 584, then repeat: 5840 / 777

Moving on to step 4:
If we divide 5840 by 777, we get 7 and a remainder of 401.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 401 after subtracting 5439 from 5840.
Fetch the next digit (3) from the dividend, attach it to 401 and continue: 4013 / 777

Moving on to step 5:
When dividing 4013 by 777, we get 5 with a remainder of 128.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 3885 from 4013, we get 128.
Include the next digit (6) from the dividend after 128, then repeat: 1286 / 777

Step 6:
If we divide 1286 by 777, we get 1 and a remainder of 509.
Use 1 as the next digit of our solution. 
Result so far: 751.0
If we subtract 777 from 1286, we get 509.
Include the next digit (5) from the dividend after 509, then repeat: 5095 / 777

On to step 7:
If we divide 5095 by 777, we get 6 and a remainder of 433.
Use 6 as the next digit of our solution. 
Result so far: 7516.0
If we subtract 4662 from 5095, we get 433.
Fetch the next digit (4) from the dividend, attach it to 433 and continue: 4334 / 777

Let's proceed to step 8:
4334 divided by 777 is 5 with a remainder of 449.
Record the quotient 5 as the next digit in the result. 
Result so far: 75165.0
Deduct 3885 from 4334 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 9:
777 goes into 4490 5 times with a remainder of 605.
Write down 5 as next digit of the result. 
Result so far: 75165.5
If we subtract 3885 from 4490, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 10:
If we divide 6050 by 777, we get 7 and a remainder of 611.
Use 7 as the next digit of our solution. 
Result so far: 75165.57
Subtracting 5439 from 6050 leaves us with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Advancing to step 11:
The number 777 fits into 6110 7 times, leaving a remainder of 671.
Put 7 as the next digit of the answer. 
Result so far: 75165.577
Deduct 5439 from 6110 and we're left with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Our division results in 75165.577 with a remaining 0.0671.
