77638654 ÷ 358 
Our goal is to divide 77638654 by 358.

Moving on to step 1:
The number 358 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 358

Advancing to step 2:
The number 358 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 358

Let's proceed to step 3:
When dividing 776 by 358, we get 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 716 from 776 to get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 358

On to step 4:
603 divided by 358 is 1 with a remainder of 245.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 358 away from 603, we end up with 245.
Include the next digit (8) from the dividend after 245, then repeat: 2458 / 358

On to step 5:
The number 358 fits into 2458 6 times, leaving a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we subtract 2148 from 2458, we get 310.
Append the next digit (6) from the dividend to 310 and continue with: 3106 / 358

Going ahead to step 6:
3106 divided by 358 is 8 with a remainder of 242.
The next digit of our result is 8. 
Result so far: 2168.0
Deduct 2864 from 3106 and we're left with 242.
Take the next digit (5) from the dividend and append it to 242, then repeat: 2425 / 358

On to step 7:
358 can be fit into 2425 6 times, resulting in a remainder of 277.
Put 6 as the next digit of the answer. 
Result so far: 21686.0
If we take 2148 away from 2425, we end up with 277.
Include the next digit (4) from the dividend after 277, then repeat: 2774 / 358

Going ahead to step 8:
When dividing 2774 by 358, we get 7 with a remainder of 268.
Use 7 as the next digit of our solution. 
Result so far: 216867.0
Subtract 2506 from 2774 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 9:
If we divide 2680 by 358, we get 7 and a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 216867.7
If we subtract 2506 from 2680, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 10:
When dividing 1740 by 358, we get 4 with a remainder of 308.
The next digit of our result is 4. 
Result so far: 216867.74
If we subtract 1432 from 1740, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 11:
3080 divided by 358 is 8 with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 216867.748
The remainder is 216 after subtracting 2864 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
When dividing 2160 by 358, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 216867.7486
Deduct 2148 from 2160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
120 divided by 358 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 216867.7486
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
358 goes into 1200 3 times with a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 216867.748603
If we take 1074 away from 1200, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 15:
When dividing 1260 by 358, we get 3 with a remainder of 186.
Write down 3 as next digit of the result. 
Result so far: 216867.7486033
If we take 1074 away from 1260, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

In conclusion, the division gives 216867.7486033 with a balance of 1.86e-06.
