Let's divide 40156539 by 679
We want to divide 40156539 by 679.

On to step 1:
679 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
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 679

On to step 2:
40 divided by 679 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 679

Advancing to step 3:
679 can be fit into 401 0 times, resulting in a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 401 and we're left with 401.
Grab the next digit (5) from the dividend, add it to 401, then carry on: 4015 / 679

Let's proceed to step 4:
If we divide 4015 by 679, we get 5 and a remainder of 620.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3395 away from 4015, we end up with 620.
Take the next digit (6) from the dividend and append it to 620, then repeat: 6206 / 679

Step 5:
If we divide 6206 by 679, we get 9 and a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 6111 from 6206 leaves us with 95.
Append the next digit (5) from the dividend to 95 and continue with: 955 / 679

On to step 6:
955 divided by 679 is 1 with a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 591.0
Subtract 679 from 955 to get 276.
Fetch the next digit (3) from the dividend, attach it to 276 and continue: 2763 / 679

Step 7:
The number 679 fits into 2763 4 times, leaving a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 5914.0
Subtracting 2716 from 2763 leaves us with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 679

On to step 8:
The number 679 fits into 479 0 times, leaving a remainder of 479.
Record the quotient 0 as the next digit in the result. 
Result so far: 59140.0
Deduct 0 from 479 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 9:
679 can be fit into 4790 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 59140.7
Deduct 4753 from 4790 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
If we divide 370 by 679, we get 0 and a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 59140.7
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 11:
When dividing 3700 by 679, we get 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 59140.705
Subtract 3395 from 3700 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 12:
The number 679 fits into 3050 4 times, leaving a remainder of 334.
The next digit of our result is 4. 
Result so far: 59140.7054
If we take 2716 away from 3050, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 13:
679 goes into 3340 4 times with a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 59140.70544
Deduct 2716 from 3340 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The final outcome is 59140.70544, with a leftover of 0.000624.
