We're dividing 42597894 by 921 
We're looking to find how many times 921 goes into 42597894.

Step 1:
921 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 921

Going ahead to step 2:
42 divided by 921 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 921

Step 3:
The number 921 fits into 425 0 times, leaving a remainder of 425.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Append the next digit (9) from the dividend to 425 and continue with: 4259 / 921

Let's proceed to step 4:
When dividing 4259 by 921, we get 4 with a remainder of 575.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 575 after subtracting 3684 from 4259.
Fetch the next digit (7) from the dividend, attach it to 575 and continue: 5757 / 921

Step 5:
When dividing 5757 by 921, we get 6 with a remainder of 231.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 5526 from 5757 leaves us with 231.
Include the next digit (8) from the dividend after 231, then repeat: 2318 / 921

On to step 6:
2318 divided by 921 is 2 with a remainder of 476.
Put 2 as the next digit of the answer. 
Result so far: 462.0
If we take 1842 away from 2318, we end up with 476.
Take the next digit (9) from the dividend and append it to 476, then repeat: 4769 / 921

Step 7:
When dividing 4769 by 921, we get 5 with a remainder of 164.
Put 5 as the next digit of the answer. 
Result so far: 4625.0
Deduct 4605 from 4769 and we're left with 164.
Fetch the next digit (4) from the dividend, attach it to 164 and continue: 1644 / 921

Moving on to step 8:
If we divide 1644 by 921, we get 1 and a remainder of 723.
Write down 1 as next digit of the result. 
Result so far: 46251.0
Subtract 921 from 1644 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 9:
The number 921 fits into 7230 7 times, leaving a remainder of 783.
The next digit of our result is 7. 
Result so far: 46251.7
Subtract 6447 from 7230 to get 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

On to step 10:
If we divide 7830 by 921, we get 8 and a remainder of 462.
The next digit of our result is 8. 
Result so far: 46251.78
If we take 7368 away from 7830, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 11:
The number 921 fits into 4620 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 46251.785
Subtracting 4605 from 4620 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
If we divide 150 by 921, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 46251.785
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 13:
If we divide 1500 by 921, we get 1 and a remainder of 579.
The next digit of our result is 1. 
Result so far: 46251.78501
Deduct 921 from 1500 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Let's proceed to step 14:
921 goes into 5790 6 times with a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 46251.785016
If we subtract 5526 from 5790, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 15:
921 can be fit into 2640 2 times, resulting in a remainder of 798.
Write down 2 as next digit of the result. 
Result so far: 46251.7850162
Subtract 1842 from 2640 to get 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Going ahead to step 16:
When dividing 7980 by 921, we get 8 with a remainder of 612.
The next digit of our result is 8. 
Result so far: 46251.78501628
The remainder is 612 after subtracting 7368 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The final outcome is 46251.78501628, with a leftover of 6.12e-07.
