41983990 ÷ 426 
Our goal is to divide 41983990 by 426.

Step 1:
426 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 426

Advancing to step 2:
The number 426 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 426

Advancing to step 3:
426 can be fit into 419 0 times, resulting in a remainder of 419.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 419, we end up with 419.
Append the next digit (8) from the dividend to 419 and continue with: 4198 / 426

Advancing to step 4:
4198 divided by 426 is 9 with a remainder of 364.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 364 after subtracting 3834 from 4198.
Take the next digit (3) from the dividend and append it to 364, then repeat: 3643 / 426

Moving on to step 5:
When dividing 3643 by 426, we get 8 with a remainder of 235.
The next digit of our result is 8. 
Result so far: 98.0
The remainder is 235 after subtracting 3408 from 3643.
Bring next digit (9) of the dividend behind the 235 and repeat the process: 2359 / 426

Let's proceed to step 6:
426 can be fit into 2359 5 times, resulting in a remainder of 229.
Write down 5 as next digit of the result. 
Result so far: 985.0
If we subtract 2130 from 2359, we get 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 426

Moving on to step 7:
426 goes into 2299 5 times with a remainder of 169.
The next digit of our result is 5. 
Result so far: 9855.0
If we subtract 2130 from 2299, we get 169.
Bring next digit (0) of the dividend behind the 169 and repeat the process: 1690 / 426

Going ahead to step 8:
If we divide 1690 by 426, we get 3 and a remainder of 412.
The number 3 becomes the next digit in our result. 
Result so far: 98553.0
If we take 1278 away from 1690, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 9:
The number 426 fits into 4120 9 times, leaving a remainder of 286.
Put 9 as the next digit of the answer. 
Result so far: 98553.9
If we take 3834 away from 4120, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
When dividing 2860 by 426, we get 6 with a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 98553.96
Deduct 2556 from 2860 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
426 goes into 3040 7 times with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 98553.967
Deduct 2982 from 3040 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
580 divided by 426 is 1 with a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 98553.9671
Subtracting 426 from 580 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 13:
If we divide 1540 by 426, we get 3 and a remainder of 262.
The number 3 becomes the next digit in our result. 
Result so far: 98553.96713
Deduct 1278 from 1540 and we're left with 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 14:
If we divide 2620 by 426, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 98553.967136
If we take 2556 away from 2620, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
426 can be fit into 640 1 times, resulting in a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 98553.9671361
If we subtract 426 from 640, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 16:
If we divide 2140 by 426, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 98553.96713615
If we subtract 2130 from 2140, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 98553.96713615 with a remainder of 1e-08.
