We divide 77666999 by 158
We want to divide 77666999 by 158.

Moving on to step 1:
158 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our 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

On to step 2:
158 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
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 / 158

Moving on to step 3:
158 can be fit into 776 4 times, resulting in a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 632 from 776 leaves us with 144.
Grab the next digit (6) from the dividend, add it to 144, then carry on: 1446 / 158

On to step 4:
When dividing 1446 by 158, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 1422 from 1446 and we're left with 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 158

Moving on to step 5:
246 divided by 158 is 1 with a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 491.0
If we take 158 away from 246, we end up with 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 158

Step 6:
889 divided by 158 is 5 with a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 4915.0
Subtract 790 from 889 to get 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 158

Step 7:
If we divide 999 by 158, we get 6 and a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 49156.0
If we subtract 948 from 999, we get 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 158

Advancing to step 8:
158 goes into 519 3 times with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 491563.0
The remainder is 45 after subtracting 474 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
If we divide 450 by 158, we get 2 and a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 491563.2
If we take 316 away from 450, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
When dividing 1340 by 158, we get 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 491563.28
The remainder is 76 after subtracting 1264 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
760 divided by 158 is 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 491563.284
The remainder is 128 after subtracting 632 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
When dividing 1280 by 158, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 491563.2848
If we subtract 1264 from 1280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
If we divide 160 by 158, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 491563.28481
Subtract 158 from 160 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
If we divide 20 by 158, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 491563.28481
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
The number 158 fits into 200 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 491563.2848101
Subtract 158 from 200 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 16:
When dividing 420 by 158, we get 2 with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 491563.28481012
If we subtract 316 from 420, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 491563.28481012 with a remaining 1.04e-07.
