450138 divided by 77 
We want to divide 450138 by 77.

Moving on to step 1:
4 divided by 77 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 77

On to step 2:
When dividing 45 by 77, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 77

Moving on to step 3:
77 can be fit into 450 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 385 from 450 leaves us with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 77

Advancing to step 4:
77 can be fit into 651 8 times, resulting in a remainder of 35.
The next digit of our result is 8. 
Result so far: 58.0
If we take 616 away from 651, we end up with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 77

Advancing to step 5:
If we divide 353 by 77, we get 4 and a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 584.0
Deduct 308 from 353 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 77

On to step 6:
77 goes into 458 5 times with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 5845.0

Put 9 as the next digit of the answer. 
Result so far: 5845.9
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
When dividing 370 by 77, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 5845.94
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
77 goes into 620 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5845.948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 77, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5845.948
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
77 goes into 400 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5845.94805
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
150 divided by 77 is 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 5845.948051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 13:
When dividing 730 by 77, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 5845.9480519
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
77 can be fit into 370 4 times, resulting in a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 5845.94805194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 5845.94805194, with a leftover of 6.2e-08.
