3981 divided by 29 
We want to figure out the number of times 3981 can be divided by 29.

Advancing to step 1:
When dividing 3 by 29, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 29

Step 2:
29 can be fit into 39 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 29 away from 39, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 29

Let's proceed to step 3:
When dividing 108 by 29, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 87 from 108 leaves us with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 29

On to step 4:
29 goes into 211 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 137.0
If we take 203 away from 211, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 5:
If we divide 80 by 29, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 137.2
Deduct 58 from 80 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 6:
When dividing 220 by 29, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 137.27
Deduct 203 from 220 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
29 can be fit into 170 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 137.275
Subtracting 145 from 170 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
29 can be fit into 250 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 137.2758
Subtract 232 from 250 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 29, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 137.27586
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 29 fits into 60 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 137.275862
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 29, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 137.275862
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 29 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 137.27586206
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 137.27586206 with a remaining 2.6e-08.
