We're dividing 25986877 by 151 
We're looking to find how many times 151 goes into 25986877.

Let's proceed to step 1:
151 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 151

On to step 2:
When dividing 25 by 151, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 151

Moving on to step 3:
151 can be fit into 259 1 times, resulting in a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 151 away from 259, we end up with 108.
Take the next digit (8) from the dividend and append it to 108, then repeat: 1088 / 151

Going ahead to step 4:
151 can be fit into 1088 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 1057 from 1088 to get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 151

Step 5:
The number 151 fits into 316 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 172.0
If we take 302 away from 316, we end up with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 151

Advancing to step 6:
The number 151 fits into 148 0 times, leaving a remainder of 148.
Record the quotient 0 as the next digit in the result. 
Result so far: 1720.0
Subtracting 0 from 148 leaves us with 148.
Include the next digit (7) from the dividend after 148, then repeat: 1487 / 151

On to step 7:
If we divide 1487 by 151, we get 9 and a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 17209.0
The remainder is 128 after subtracting 1359 from 1487.
Fetch the next digit (7) from the dividend, attach it to 128 and continue: 1287 / 151

Advancing to step 8:
151 can be fit into 1287 8 times, resulting in a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 172098.0
If we subtract 1208 from 1287, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
The number 151 fits into 790 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 172098.5
If we take 755 away from 790, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
The number 151 fits into 350 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 172098.52
If we subtract 302 from 350, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
151 goes into 480 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 172098.523
If we subtract 453 from 480, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
270 divided by 151 is 1 with a remainder of 119.
The next digit of our result is 1. 
Result so far: 172098.5231
Deduct 151 from 270 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 13:
If we divide 1190 by 151, we get 7 and a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 172098.52317
Deduct 1057 from 1190 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 14:
The number 151 fits into 1330 8 times, leaving a remainder of 122.
Put 8 as the next digit of the answer. 
Result so far: 172098.523178
The remainder is 122 after subtracting 1208 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 15:
1220 divided by 151 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 172098.5231788
Subtract 1208 from 1220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 172098.5231788, with a leftover of 1.2e-07.
