We're dividing 40939110 by 939 
Our goal is to divide 40939110 by 939.

Let's proceed to step 1:
939 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 939

On to step 2:
939 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 939

On to step 3:
If we divide 409 by 939, we get 0 and a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 409 to get 409.
Include the next digit (3) from the dividend after 409, then repeat: 4093 / 939

Step 4:
939 can be fit into 4093 4 times, resulting in a remainder of 337.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3756 from 4093 to get 337.
Grab the next digit (9) from the dividend, add it to 337, then carry on: 3379 / 939

Advancing to step 5:
939 can be fit into 3379 3 times, resulting in a remainder of 562.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 2817 from 3379 leaves us with 562.
Append the next digit (1) from the dividend to 562 and continue with: 5621 / 939

On to step 6:
The number 939 fits into 5621 5 times, leaving a remainder of 926.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we take 4695 away from 5621, we end up with 926.
Take the next digit (1) from the dividend and append it to 926, then repeat: 9261 / 939

Advancing to step 7:
The number 939 fits into 9261 9 times, leaving a remainder of 810.
Write down 9 as next digit of the result. 
Result so far: 4359.0
Subtract 8451 from 9261 to get 810.
Include the next digit (0) from the dividend after 810, then repeat: 8100 / 939

Step 8:
939 can be fit into 8100 8 times, resulting in a remainder of 588.
The next digit of our result is 8. 
Result so far: 43598.0
Subtract 7512 from 8100 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 9:
939 can be fit into 5880 6 times, resulting in a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 43598.6
If we subtract 5634 from 5880, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 10:
If we divide 2460 by 939, we get 2 and a remainder of 582.
The number 2 becomes the next digit in our result. 
Result so far: 43598.62
Subtract 1878 from 2460 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 11:
The number 939 fits into 5820 6 times, leaving a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 43598.626
Subtracting 5634 from 5820 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 12:
939 can be fit into 1860 1 times, resulting in a remainder of 921.
Record the quotient 1 as the next digit in the result. 
Result so far: 43598.6261
If we subtract 939 from 1860, we get 921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9210, and continue the process.

Moving on to step 13:
939 can be fit into 9210 9 times, resulting in a remainder of 759.
The number 9 becomes the next digit in our result. 
Result so far: 43598.62619
The remainder is 759 after subtracting 8451 from 9210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

On to step 14:
939 goes into 7590 8 times with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 43598.626198
Subtracting 7512 from 7590 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 15:
If we divide 780 by 939, we get 0 and a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 43598.626198
If we take 0 away from 780, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 16:
939 goes into 7800 8 times with a remainder of 288.
The next digit of our result is 8. 
Result so far: 43598.62619808
Deduct 7512 from 7800 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 43598.62619808, with a leftover of 2.88e-07.
