39432425 ÷ 921 
We want to divide 39432425 by 921.

Let's proceed to step 1:
The number 921 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 921

Let's proceed to step 2:
921 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 921

Going ahead to step 3:
When dividing 394 by 921, we get 0 with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 394, we end up with 394.
Grab the next digit (3) from the dividend, add it to 394, then carry on: 3943 / 921

Going ahead to step 4:
921 goes into 3943 4 times with a remainder of 259.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3684 away from 3943, we end up with 259.
Fetch the next digit (2) from the dividend, attach it to 259 and continue: 2592 / 921

Step 5:
The number 921 fits into 2592 2 times, leaving a remainder of 750.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 750 after subtracting 1842 from 2592.
Fetch the next digit (4) from the dividend, attach it to 750 and continue: 7504 / 921

Moving on to step 6:
7504 divided by 921 is 8 with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Subtract 7368 from 7504 to get 136.
Take the next digit (2) from the dividend and append it to 136, then repeat: 1362 / 921

Step 7:
1362 divided by 921 is 1 with a remainder of 441.
Use 1 as the next digit of our solution. 
Result so far: 4281.0
If we subtract 921 from 1362, we get 441.
Append the next digit (5) from the dividend to 441 and continue with: 4415 / 921

Moving on to step 8:
The number 921 fits into 4415 4 times, leaving a remainder of 731.
Put 4 as the next digit of the answer. 
Result so far: 42814.0
Subtract 3684 from 4415 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Advancing to step 9:
When dividing 7310 by 921, we get 7 with a remainder of 863.
Write down 7 as next digit of the result. 
Result so far: 42814.7
Subtract 6447 from 7310 to get 863.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Advancing to step 10:
8630 divided by 921 is 9 with a remainder of 341.
Write down 9 as next digit of the result. 
Result so far: 42814.79
Deduct 8289 from 8630 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 11:
3410 divided by 921 is 3 with a remainder of 647.
Use 3 as the next digit of our solution. 
Result so far: 42814.793
The remainder is 647 after subtracting 2763 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

On to step 12:
921 can be fit into 6470 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 42814.7937
Deduct 6447 from 6470 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
921 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 42814.7937
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 14:
If we divide 2300 by 921, we get 2 and a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 42814.793702
If we take 1842 away from 2300, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 15:
921 goes into 4580 4 times with a remainder of 896.
Use 4 as the next digit of our solution. 
Result so far: 42814.7937024
If we subtract 3684 from 4580, we get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

On to step 16:
When dividing 8960 by 921, we get 9 with a remainder of 671.
Put 9 as the next digit of the answer. 
Result so far: 42814.79370249
Subtract 8289 from 8960 to get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

The final result is 42814.79370249 with a remainder of 6.71e-07.
