Let's divide 139521 by 41
Let's see how many times 41 fits into 139521.

Advancing to step 1:
1 divided by 41 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 41

Step 2:
If we divide 13 by 41, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 41

On to step 3:
41 can be fit into 139 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 123 away from 139, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 41

Moving on to step 4:
165 divided by 41 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 1 after subtracting 164 from 165.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 41

Let's proceed to step 5:
12 divided by 41 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 340.0
Subtract 0 from 12 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 41

On to step 6:
41 can be fit into 121 2 times, resulting in a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 3402.0
If we take 82 away from 121, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
If we divide 390 by 41, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 3402.9
The remainder is 21 after subtracting 369 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
41 can be fit into 210 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 3402.95
The remainder is 5 after subtracting 205 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
41 goes into 50 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 3402.951
Subtracting 41 from 50 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
If we divide 90 by 41, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3402.9512
If we subtract 82 from 90, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 41, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 3402.95121
Subtracting 41 from 80 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 12:
When dividing 390 by 41, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 3402.951219
Deduct 369 from 390 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
The number 41 fits into 210 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3402.9512195
Subtract 205 from 210 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
41 can be fit into 50 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 3402.95121951
If we take 41 away from 50, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 3402.95121951, with a leftover of 9e-09.
