40837983 ÷ 986 
We want to divide 40837983 by 986.

On to step 1:
The number 986 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 986

Moving on to step 2:
If we divide 40 by 986, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 986

Step 3:
The number 986 fits into 408 0 times, leaving a remainder of 408.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 408, we end up with 408.
Include the next digit (3) from the dividend after 408, then repeat: 4083 / 986

Advancing to step 4:
4083 divided by 986 is 4 with a remainder of 139.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3944 from 4083, we get 139.
Take the next digit (7) from the dividend and append it to 139, then repeat: 1397 / 986

Moving on to step 5:
1397 divided by 986 is 1 with a remainder of 411.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 986 from 1397 leaves us with 411.
Fetch the next digit (9) from the dividend, attach it to 411 and continue: 4119 / 986

On to step 6:
When dividing 4119 by 986, we get 4 with a remainder of 175.
Record the quotient 4 as the next digit in the result. 
Result so far: 414.0
Subtracting 3944 from 4119 leaves us with 175.
Append the next digit (8) from the dividend to 175 and continue with: 1758 / 986

Moving on to step 7:
If we divide 1758 by 986, we get 1 and a remainder of 772.
Use 1 as the next digit of our solution. 
Result so far: 4141.0
If we take 986 away from 1758, we end up with 772.
Fetch the next digit (3) from the dividend, attach it to 772 and continue: 7723 / 986

Step 8:
986 goes into 7723 7 times with a remainder of 821.
Put 7 as the next digit of the answer. 
Result so far: 41417.0
If we take 6902 away from 7723, 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.

Going ahead to step 9:
986 can be fit into 8210 8 times, resulting in a remainder of 322.
The number 8 becomes the next digit in our result. 
Result so far: 41417.8
Subtracting 7888 from 8210 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 10:
The number 986 fits into 3220 3 times, leaving a remainder of 262.
Write down 3 as next digit of the result. 
Result so far: 41417.83
If we subtract 2958 from 3220, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 11:
When dividing 2620 by 986, we get 2 with a remainder of 648.
The number 2 becomes the next digit in our result. 
Result so far: 41417.832
Subtract 1972 from 2620 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 12:
If we divide 6480 by 986, we get 6 and a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 41417.8326
Subtracting 5916 from 6480 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 13:
5640 divided by 986 is 5 with a remainder of 710.
Put 5 as the next digit of the answer. 
Result so far: 41417.83265
If we subtract 4930 from 5640, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 14:
986 can be fit into 7100 7 times, resulting in a remainder of 198.
Put 7 as the next digit of the answer. 
Result so far: 41417.832657
The remainder is 198 after subtracting 6902 from 7100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 15:
When dividing 1980 by 986, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41417.8326572
The remainder is 8 after subtracting 1972 from 1980.
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 16:
80 divided by 986 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 41417.8326572
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 41417.8326572 with a remaining 8e-08.
