We look at the division of 72374780 by 86 
We want to divide 72374780 by 86.

Advancing to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 86

Step 2:
The number 86 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 86

On to step 3:
723 divided by 86 is 8 with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 688 from 723 leaves us with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 86

Step 4:
86 can be fit into 357 4 times, resulting in a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 344 from 357 leaves us with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 86

Step 5:
The number 86 fits into 134 1 times, leaving a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
If we take 86 away from 134, we end up with 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 86

Going ahead to step 6:
86 goes into 487 5 times with a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 8415.0
If we take 430 away from 487, we end up with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 86

On to step 7:
If we divide 578 by 86, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 84156.0
If we subtract 516 from 578, we get 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 86

Let's proceed to step 8:
86 goes into 620 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 841567.0
If we take 602 away from 620, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 86, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 841567.2
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
If we divide 80 by 86, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 841567.2
If we take 0 away from 80, we end up 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.

Moving on to step 11:
The number 86 fits into 800 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 841567.209
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
If we divide 260 by 86, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 841567.2093
Subtracting 258 from 260 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.

Let's proceed to step 13:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 841567.2093
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 841567.209302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 15:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 841567.2093023
If we take 258 away from 280, we end up 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.

Let's proceed to step 16:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 841567.20930232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 841567.20930232, with a leftover of 4.8e-08.
