15475891 ÷ 943 
We want to figure out the number of times 15475891 can be divided by 943.

Step 1:
943 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 943

On to step 2:
943 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 943

Step 3:
When dividing 154 by 943, we get 0 with a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Fetch the next digit (7) from the dividend, attach it to 154 and continue: 1547 / 943

On to step 4:
When dividing 1547 by 943, we get 1 with a remainder of 604.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 943 from 1547, we get 604.
Include the next digit (5) from the dividend after 604, then repeat: 6045 / 943

Going ahead to step 5:
943 goes into 6045 6 times with a remainder of 387.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 5658 from 6045 to get 387.
Append the next digit (8) from the dividend to 387 and continue with: 3878 / 943

Going ahead to step 6:
If we divide 3878 by 943, we get 4 and a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtract 3772 from 3878 to get 106.
Bring next digit (9) of the dividend behind the 106 and repeat the process: 1069 / 943

Moving on to step 7:
The number 943 fits into 1069 1 times, leaving a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 1641.0
If we take 943 away from 1069, we end up with 126.
Grab the next digit (1) from the dividend, add it to 126, then carry on: 1261 / 943

Moving on to step 8:
If we divide 1261 by 943, we get 1 and a remainder of 318.
Record the quotient 1 as the next digit in the result. 
Result so far: 16411.0
The remainder is 318 after subtracting 943 from 1261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 9:
3180 divided by 943 is 3 with a remainder of 351.
The next digit of our result is 3. 
Result so far: 16411.3
Subtract 2829 from 3180 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 10:
If we divide 3510 by 943, we get 3 and a remainder of 681.
Write down 3 as next digit of the result. 
Result so far: 16411.33
Subtract 2829 from 3510 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final result is 16411.33 with a remainder of 0.681.
