Let's divide 31458521 by 849
We want to figure out the number of times 31458521 can be divided by 849.

Let's proceed to step 1:
3 divided by 849 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 849

Step 2:
849 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 849

Moving on to step 3:
The number 849 fits into 314 0 times, leaving a remainder of 314.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 314 to get 314.
Append the next digit (5) from the dividend to 314 and continue with: 3145 / 849

Advancing to step 4:
849 can be fit into 3145 3 times, resulting in a remainder of 598.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2547 from 3145, we get 598.
Include the next digit (8) from the dividend after 598, then repeat: 5988 / 849

Let's proceed to step 5:
5988 divided by 849 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 45 after subtracting 5943 from 5988.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 849

Step 6:
If we divide 455 by 849, we get 0 and a remainder of 455.
Write down 0 as next digit of the result. 
Result so far: 370.0
Subtract 0 from 455 to get 455.
Fetch the next digit (2) from the dividend, attach it to 455 and continue: 4552 / 849

On to step 7:
The number 849 fits into 4552 5 times, leaving a remainder of 307.
The next digit of our result is 5. 
Result so far: 3705.0
If we take 4245 away from 4552, we end up with 307.
Grab the next digit (1) from the dividend, add it to 307, then carry on: 3071 / 849

Let's proceed to step 8:
849 can be fit into 3071 3 times, resulting in a remainder of 524.
Put 3 as the next digit of the answer. 
Result so far: 37053.0
If we take 2547 away from 3071, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 9:
5240 divided by 849 is 6 with a remainder of 146.
The next digit of our result is 6. 
Result so far: 37053.6
Subtract 5094 from 5240 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 10:
If we divide 1460 by 849, we get 1 and a remainder of 611.
Use 1 as the next digit of our solution. 
Result so far: 37053.61
Subtract 849 from 1460 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Moving on to step 11:
849 can be fit into 6110 7 times, resulting in a remainder of 167.
Record the quotient 7 as the next digit in the result. 
Result so far: 37053.617
Deduct 5943 from 6110 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 12:
The number 849 fits into 1670 1 times, leaving a remainder of 821.
The number 1 becomes the next digit in our result. 
Result so far: 37053.6171
If we take 849 away from 1670, we end up with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Moving on to step 13:
849 can be fit into 8210 9 times, resulting in a remainder of 569.
The number 9 becomes the next digit in our result. 
Result so far: 37053.61719
If we subtract 7641 from 8210, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Step 14:
5690 divided by 849 is 6 with a remainder of 596.
The number 6 becomes the next digit in our result. 
Result so far: 37053.617196
If we subtract 5094 from 5690, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 15:
The number 849 fits into 5960 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 37053.6171967
The remainder is 17 after subtracting 5943 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 16:
The number 849 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 37053.6171967
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 37053.6171967, with a leftover of 1.7e-07.
