We look at the division of 4166129 by 945 
Let's see how many times 945 fits into 4166129.

Let's proceed to step 1:
When dividing 4 by 945, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 945

Going ahead to step 2:
If we divide 41 by 945, we get 0 and a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 945

Step 3:
If we divide 416 by 945, we get 0 and a remainder of 416.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 416 leaves us with 416.
Fetch the next digit (6) from the dividend, attach it to 416 and continue: 4166 / 945

Step 4:
4166 divided by 945 is 4 with a remainder of 386.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3780 from 4166 and we're left with 386.
Include the next digit (1) from the dividend after 386, then repeat: 3861 / 945

On to step 5:
945 can be fit into 3861 4 times, resulting in a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 3780 away from 3861, we end up with 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 945

Step 6:
The number 945 fits into 812 0 times, leaving a remainder of 812.
Use 0 as the next digit of our solution. 
Result so far: 440.0
Subtract 0 from 812 to get 812.
Append the next digit (9) from the dividend to 812 and continue with: 8129 / 945

On to step 7:
If we divide 8129 by 945, we get 8 and a remainder of 569.
Use 8 as the next digit of our solution. 
Result so far: 4408.0
The remainder is 569 after subtracting 7560 from 8129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 8:
945 goes into 5690 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 4408.6
If we subtract 5670 from 5690, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 945, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 4408.6
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
The number 945 fits into 2000 2 times, leaving a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 4408.602
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
945 goes into 1100 1 times with a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 4408.6021
Subtract 945 from 1100 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
When dividing 1550 by 945, we get 1 with a remainder of 605.
The next digit of our result is 1. 
Result so far: 4408.60211
Subtract 945 from 1550 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

The final outcome is 4408.60211, with a leftover of 0.000605.
