We're dividing 77139814 by 158 
We're looking to find how many times 158 goes into 77139814.

Going ahead to step 1:
158 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 158

Advancing to step 2:
When dividing 77 by 158, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 158

Step 3:
771 divided by 158 is 4 with a remainder of 139.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 632 from 771 leaves us with 139.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 158

Let's proceed to step 4:
158 goes into 1393 8 times with a remainder of 129.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 129 after subtracting 1264 from 1393.
Bring next digit (9) of the dividend behind the 129 and repeat the process: 1299 / 158

Step 5:
When dividing 1299 by 158, we get 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 488.0
Deduct 1264 from 1299 and we're left with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 158

On to step 6:
If we divide 358 by 158, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 4882.0
If we subtract 316 from 358, we get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 158

Advancing to step 7:
421 divided by 158 is 2 with a remainder of 105.
Write down 2 as next digit of the result. 
Result so far: 48822.0
Subtracting 316 from 421 leaves us with 105.
Include the next digit (4) from the dividend after 105, then repeat: 1054 / 158

Moving on to step 8:
If we divide 1054 by 158, we get 6 and a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 488226.0
The remainder is 106 after subtracting 948 from 1054.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
158 can be fit into 1060 6 times, resulting in a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 488226.6
The remainder is 112 after subtracting 948 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
If we divide 1120 by 158, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 488226.67
Deduct 1106 from 1120 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 158 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 488226.67
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
If we divide 1400 by 158, we get 8 and a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 488226.6708
If we take 1264 away from 1400, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
1360 divided by 158 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 488226.67088
Subtracting 1264 from 1360 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 488226.67088 and a remainder of 9.6e-05.
