We divide 40138017 by 77
Our goal is to divide 40138017 by 77.

Moving on to step 1:
4 divided by 77 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 77

Let's proceed to step 2:
40 divided by 77 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 77

Let's proceed to step 3:
401 divided by 77 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 385 from 401 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 77

Let's proceed to step 4:
If we divide 163 by 77, we get 2 and a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 52.0
The remainder is 9 after subtracting 154 from 163.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 77

On to step 5:
The number 77 fits into 98 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 521.0
If we subtract 77 from 98, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 77

Advancing to step 6:
77 can be fit into 210 2 times, resulting in a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 5212.0
Deduct 154 from 210 and we're left with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 77

On to step 7:
561 divided by 77 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 52127.0
The remainder is 22 after subtracting 539 from 561.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 77

Moving on to step 8:
77 can be fit into 227 2 times, resulting in a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 521272.0
Subtracting 154 from 227 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.

Step 9:
77 can be fit into 730 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 521272.9
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.

Moving on to step 10:
When dividing 370 by 77, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 521272.94
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.

On to step 11:
If we divide 620 by 77, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 521272.948
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.

Advancing to step 12:
The number 77 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 521272.948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
77 goes into 400 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 521272.94805
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.

Going ahead to step 14:
When dividing 150 by 77, we get 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 521272.948051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 15:
If we divide 730 by 77, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 521272.9480519
Subtract 693 from 730 to 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.

Let's proceed to step 16:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 521272.94805194
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.

The final outcome is 521272.94805194, with a leftover of 6.2e-08.
