87320442 ÷ 712 
We want to figure out the number of times 87320442 can be divided by 712.

On to step 1:
712 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 712

Moving on to step 2:
712 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 712

On to step 3:
712 goes into 873 1 times with a remainder of 161.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 712 away from 873, we end up with 161.
Take the next digit (2) from the dividend and append it to 161, then repeat: 1612 / 712

Advancing to step 4:
If we divide 1612 by 712, we get 2 and a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 188 after subtracting 1424 from 1612.
Bring next digit (0) of the dividend behind the 188 and repeat the process: 1880 / 712

Let's proceed to step 5:
If we divide 1880 by 712, we get 2 and a remainder of 456.
The next digit of our result is 2. 
Result so far: 122.0
If we take 1424 away from 1880, we end up with 456.
Bring next digit (4) of the dividend behind the 456 and repeat the process: 4564 / 712

Moving on to step 6:
When dividing 4564 by 712, we get 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 1226.0
Subtract 4272 from 4564 to get 292.
Append the next digit (4) from the dividend to 292 and continue with: 2924 / 712

On to step 7:
2924 divided by 712 is 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 12264.0
Subtracting 2848 from 2924 leaves us with 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 712

On to step 8:
The number 712 fits into 762 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 122641.0
The remainder is 50 after subtracting 712 from 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
712 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 122641.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 10:
712 can be fit into 5000 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 122641.07
Subtract 4984 from 5000 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
712 can be fit into 160 0 times, resulting in a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 122641.07
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
If we divide 1600 by 712, we get 2 and a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 122641.0702
If we subtract 1424 from 1600, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 13:
712 goes into 1760 2 times with a remainder of 336.
Use 2 as the next digit of our solution. 
Result so far: 122641.07022
Deduct 1424 from 1760 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 122641.07022 with a remainder of 0.000336.
