Let's divide 83215101 by 687
We're looking to find how many times 687 goes into 83215101.

On to step 1:
If we divide 8 by 687, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 687

Let's proceed to step 2:
If we divide 83 by 687, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 687

Moving on to step 3:
687 goes into 832 1 times with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 145 after subtracting 687 from 832.
Bring next digit (1) of the dividend behind the 145 and repeat the process: 1451 / 687

On to step 4:
687 can be fit into 1451 2 times, resulting in a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1374 from 1451 to get 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 687

Advancing to step 5:
775 divided by 687 is 1 with a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 687 from 775 to get 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 687

Moving on to step 6:
If we divide 881 by 687, we get 1 and a remainder of 194.
The next digit of our result is 1. 
Result so far: 1211.0
The remainder is 194 after subtracting 687 from 881.
Fetch the next digit (0) from the dividend, attach it to 194 and continue: 1940 / 687

Step 7:
1940 divided by 687 is 2 with a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 12112.0
Subtracting 1374 from 1940 leaves us with 566.
Fetch the next digit (1) from the dividend, attach it to 566 and continue: 5661 / 687

Moving on to step 8:
687 can be fit into 5661 8 times, resulting in a remainder of 165.
The number 8 becomes the next digit in our result. 
Result so far: 121128.0
If we take 5496 away from 5661, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
The number 687 fits into 1650 2 times, leaving a remainder of 276.
The number 2 becomes the next digit in our result. 
Result so far: 121128.2
Subtracting 1374 from 1650 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 10:
687 can be fit into 2760 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 121128.24
The remainder is 12 after subtracting 2748 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
687 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 121128.24
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
If we divide 1200 by 687, we get 1 and a remainder of 513.
The next digit of our result is 1. 
Result so far: 121128.2401
Subtracting 687 from 1200 leaves us with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Let's proceed to step 13:
When dividing 5130 by 687, we get 7 with a remainder of 321.
The number 7 becomes the next digit in our result. 
Result so far: 121128.24017
Subtract 4809 from 5130 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 14:
If we divide 3210 by 687, we get 4 and a remainder of 462.
The next digit of our result is 4. 
Result so far: 121128.240174
If we subtract 2748 from 3210, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 15:
4620 divided by 687 is 6 with a remainder of 498.
The next digit of our result is 6. 
Result so far: 121128.2401746
Subtracting 4122 from 4620 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 16:
687 can be fit into 4980 7 times, resulting in a remainder of 171.
The next digit of our result is 7. 
Result so far: 121128.24017467
Subtracting 4809 from 4980 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final result is 121128.24017467 with a remainder of 1.71e-07.
