We divide 25193101 by 851
We want to divide 25193101 by 851.

On to step 1:
When dividing 2 by 851, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 851

Let's proceed to step 2:
When dividing 25 by 851, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 851

Moving on to step 3:
251 divided by 851 is 0 with a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Append the next digit (9) from the dividend to 251 and continue with: 2519 / 851

Advancing to step 4:
851 goes into 2519 2 times with a remainder of 817.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1702 away from 2519, we end up with 817.
Include the next digit (3) from the dividend after 817, then repeat: 8173 / 851

Let's proceed to step 5:
8173 divided by 851 is 9 with a remainder of 514.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 514 after subtracting 7659 from 8173.
Grab the next digit (1) from the dividend, add it to 514, then carry on: 5141 / 851

On to step 6:
If we divide 5141 by 851, we get 6 and a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Subtracting 5106 from 5141 leaves us with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 851

Moving on to step 7:
When dividing 350 by 851, we get 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 2960.0
Deduct 0 from 350 and we're left with 350.
Take the next digit (1) from the dividend and append it to 350, then repeat: 3501 / 851

Advancing to step 8:
851 can be fit into 3501 4 times, resulting in a remainder of 97.
Record the quotient 4 as the next digit in the result. 
Result so far: 29604.0
If we subtract 3404 from 3501, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
851 can be fit into 970 1 times, resulting in a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 29604.1
Subtracting 851 from 970 leaves us 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.

Advancing to step 10:
When dividing 1190 by 851, we get 1 with a remainder of 339.
The next digit of our result is 1. 
Result so far: 29604.11
Subtract 851 from 1190 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The final result is 29604.11 with a remainder of 0.339.
