We divide 75399213 by 688
We want to divide 75399213 by 688.

Going ahead to step 1:
688 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 688

On to step 2:
The number 688 fits into 75 0 times, leaving a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 688

Going ahead to step 3:
688 can be fit into 753 1 times, resulting in a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 688 from 753 leaves us with 65.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 688

Moving on to step 4:
If we divide 659 by 688, we get 0 and a remainder of 659.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 659 to get 659.
Append the next digit (9) from the dividend to 659 and continue with: 6599 / 688

Going ahead to step 5:
688 goes into 6599 9 times with a remainder of 407.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 407 after subtracting 6192 from 6599.
Include the next digit (2) from the dividend after 407, then repeat: 4072 / 688

Step 6:
The number 688 fits into 4072 5 times, leaving a remainder of 632.
Put 5 as the next digit of the answer. 
Result so far: 1095.0
Subtracting 3440 from 4072 leaves us with 632.
Grab the next digit (1) from the dividend, add it to 632, then carry on: 6321 / 688

Let's proceed to step 7:
When dividing 6321 by 688, we get 9 with a remainder of 129.
The next digit of our result is 9. 
Result so far: 10959.0
The remainder is 129 after subtracting 6192 from 6321.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 688

Advancing to step 8:
If we divide 1293 by 688, we get 1 and a remainder of 605.
The next digit of our result is 1. 
Result so far: 109591.0
If we take 688 away from 1293, we end up with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 9:
6050 divided by 688 is 8 with a remainder of 546.
Write down 8 as next digit of the result. 
Result so far: 109591.8
Subtracting 5504 from 6050 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 10:
If we divide 5460 by 688, we get 7 and a remainder of 644.
Write down 7 as next digit of the result. 
Result so far: 109591.87
If we subtract 4816 from 5460, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 11:
688 goes into 6440 9 times with a remainder of 248.
Use 9 as the next digit of our solution. 
Result so far: 109591.879
Subtract 6192 from 6440 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
The number 688 fits into 2480 3 times, leaving a remainder of 416.
Record the quotient 3 as the next digit in the result. 
Result so far: 109591.8793
If we subtract 2064 from 2480, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
If we divide 4160 by 688, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 109591.87936
If we subtract 4128 from 4160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
The number 688 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 109591.87936
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 15:
When dividing 3200 by 688, we get 4 with a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 109591.8793604
Subtract 2752 from 3200 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 16:
4480 divided by 688 is 6 with a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 109591.87936046
Deduct 4128 from 4480 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 109591.87936046, with a leftover of 3.52e-07.
