27902986 ÷ 158 
We're looking to find how many times 158 goes into 27902986.

Moving on to step 1:
158 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 158

Step 2:
The number 158 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 158

On to step 3:
When dividing 279 by 158, we get 1 with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 158 from 279 to get 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 158

Moving on to step 4:
158 can be fit into 1210 7 times, resulting in a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 1106 from 1210 and we're left with 104.
Take the next digit (2) from the dividend and append it to 104, then repeat: 1042 / 158

Moving on to step 5:
1042 divided by 158 is 6 with a remainder of 94.
The next digit of our result is 6. 
Result so far: 176.0
Subtract 948 from 1042 to get 94.
Fetch the next digit (9) from the dividend, attach it to 94 and continue: 949 / 158

Step 6:
949 divided by 158 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1766.0
Subtracting 948 from 949 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 158

Advancing to step 7:
18 divided by 158 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 17660.0
Subtract 0 from 18 to get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 158

On to step 8:
186 divided by 158 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 176601.0
The remainder is 28 after subtracting 158 from 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
When dividing 280 by 158, we get 1 with a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 176601.1
If we subtract 158 from 280, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 10:
When dividing 1220 by 158, we get 7 with a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 176601.17
If we subtract 1106 from 1220, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
When dividing 1140 by 158, we get 7 with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 176601.177
If we take 1106 away from 1140, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 176601.177 with a remaining 0.0034.
