We look at the division of 77064940 by 438 
We want to divide 77064940 by 438.

Moving on to step 1:
7 divided by 438 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 438

Step 2:
438 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 438

Advancing to step 3:
If we divide 770 by 438, we get 1 and a remainder of 332.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 332 after subtracting 438 from 770.
Append the next digit (6) from the dividend to 332 and continue with: 3326 / 438

Step 4:
3326 divided by 438 is 7 with a remainder of 260.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 3066 from 3326 and we're left with 260.
Include the next digit (4) from the dividend after 260, then repeat: 2604 / 438

On to step 5:
If we divide 2604 by 438, we get 5 and a remainder of 414.
Use 5 as the next digit of our solution. 
Result so far: 175.0
If we subtract 2190 from 2604, we get 414.
Bring next digit (9) of the dividend behind the 414 and repeat the process: 4149 / 438

Step 6:
The number 438 fits into 4149 9 times, leaving a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 1759.0
Subtract 3942 from 4149 to get 207.
Include the next digit (4) from the dividend after 207, then repeat: 2074 / 438

Advancing to step 7:
438 can be fit into 2074 4 times, resulting in a remainder of 322.
Put 4 as the next digit of the answer. 
Result so far: 17594.0
If we take 1752 away from 2074, we end up with 322.
Append the next digit (0) from the dividend to 322 and continue with: 3220 / 438

Moving on to step 8:
If we divide 3220 by 438, we get 7 and a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 175947.0
If we take 3066 away from 3220, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 9:
1540 divided by 438 is 3 with a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 175947.3
If we take 1314 away from 1540, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
When dividing 2260 by 438, we get 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 175947.35
Deduct 2190 from 2260 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
438 can be fit into 700 1 times, resulting in a remainder of 262.
The number 1 becomes the next digit in our result. 
Result so far: 175947.351
If we take 438 away from 700, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 12:
438 goes into 2620 5 times with a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 175947.3515
If we take 2190 away from 2620, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 13:
438 goes into 4300 9 times with a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 175947.35159
If we take 3942 away from 4300, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 14:
438 goes into 3580 8 times with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 175947.351598
If we take 3504 away from 3580, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 15:
If we divide 760 by 438, we get 1 and a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 175947.3515981
If we take 438 away from 760, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 16:
The number 438 fits into 3220 7 times, leaving a remainder of 154.
Use 7 as the next digit of our solution. 
Result so far: 175947.35159817
Subtracting 3066 from 3220 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 175947.35159817 with a remainder of 1.54e-07.
