We look at the division of 18102574 by 946 
Our goal is to divide 18102574 by 946.

On to step 1:
When dividing 1 by 946, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 946

Step 2:
946 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 946

Step 3:
946 can be fit into 181 0 times, resulting in a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Fetch the next digit (0) from the dividend, attach it to 181 and continue: 1810 / 946

Moving on to step 4:
When dividing 1810 by 946, we get 1 with a remainder of 864.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 946 from 1810 to get 864.
Fetch the next digit (2) from the dividend, attach it to 864 and continue: 8642 / 946

Step 5:
If we divide 8642 by 946, we get 9 and a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 128 after subtracting 8514 from 8642.
Bring next digit (5) of the dividend behind the 128 and repeat the process: 1285 / 946

Going ahead to step 6:
946 can be fit into 1285 1 times, resulting in a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
Deduct 946 from 1285 and we're left with 339.
Grab the next digit (7) from the dividend, add it to 339, then carry on: 3397 / 946

Advancing to step 7:
The number 946 fits into 3397 3 times, leaving a remainder of 559.
Write down 3 as next digit of the result. 
Result so far: 1913.0
If we take 2838 away from 3397, we end up with 559.
Grab the next digit (4) from the dividend, add it to 559, then carry on: 5594 / 946

Moving on to step 8:
5594 divided by 946 is 5 with a remainder of 864.
Record the quotient 5 as the next digit in the result. 
Result so far: 19135.0
Deduct 4730 from 5594 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Advancing to step 9:
When dividing 8640 by 946, we get 9 with a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 19135.9
Deduct 8514 from 8640 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
946 can be fit into 1260 1 times, resulting in a remainder of 314.
The number 1 becomes the next digit in our result. 
Result so far: 19135.91
The remainder is 314 after subtracting 946 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 11:
The number 946 fits into 3140 3 times, leaving a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 19135.913
If we subtract 2838 from 3140, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 12:
If we divide 3020 by 946, we get 3 and a remainder of 182.
Use 3 as the next digit of our solution. 
Result so far: 19135.9133
If we subtract 2838 from 3020, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 19135.9133 and a remainder of 0.00182.
