We look at the division of 73727689 by 31 
We're looking to find how many times 31 goes into 73727689.

Going ahead to step 1:
The number 31 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 31

Going ahead to step 2:
31 goes into 73 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 62 from 73, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 31

Going ahead to step 3:
If we divide 117 by 31, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 24 after subtracting 93 from 117.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 31

Advancing to step 4:
31 goes into 242 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 237.0
If we subtract 217 from 242, we get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 31

On to step 5:
When dividing 257 by 31, we get 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 2378.0
Subtracting 248 from 257 leaves us with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 31

Advancing to step 6:
96 divided by 31 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 23783.0
Deduct 93 from 96 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 31

Advancing to step 7:
When dividing 38 by 31, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 237831.0
The remainder is 7 after subtracting 31 from 38.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 31

On to step 8:
31 goes into 79 2 times with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2378312.0
If we subtract 62 from 79, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
If we divide 170 by 31, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2378312.5
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
31 goes into 150 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2378312.54
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
31 can be fit into 260 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2378312.548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
120 divided by 31 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 2378312.5483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2378312.54838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 2378312.548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2378312.548387
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2378312.54838709
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 2378312.54838709 with a balance of 2.1e-08.
