Let's divide 91085251 by 251
We want to divide 91085251 by 251.

Going ahead to step 1:
9 divided by 251 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 251

On to step 2:
251 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 251

Going ahead to step 3:
910 divided by 251 is 3 with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 753 from 910 to get 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 251

Going ahead to step 4:
When dividing 1578 by 251, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 36.0
If we take 1506 away from 1578, we end up with 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 251

Advancing to step 5:
251 goes into 725 2 times with a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 362.0
If we take 502 away from 725, we end up with 223.
Fetch the next digit (2) from the dividend, attach it to 223 and continue: 2232 / 251

Going ahead to step 6:
If we divide 2232 by 251, we get 8 and a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 3628.0
If we take 2008 away from 2232, we end up with 224.
Include the next digit (5) from the dividend after 224, then repeat: 2245 / 251

Advancing to step 7:
251 can be fit into 2245 8 times, resulting in a remainder of 237.
Record the quotient 8 as the next digit in the result. 
Result so far: 36288.0
The remainder is 237 after subtracting 2008 from 2245.
Fetch the next digit (1) from the dividend, attach it to 237 and continue: 2371 / 251

Step 8:
2371 divided by 251 is 9 with a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 362889.0
The remainder is 112 after subtracting 2259 from 2371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
The number 251 fits into 1120 4 times, leaving a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 362889.4
If we subtract 1004 from 1120, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
If we divide 1160 by 251, we get 4 and a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 362889.44
Subtract 1004 from 1160 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 362889.44 with a remaining 0.156.
