75103607 ÷ 178 
We want to divide 75103607 by 178.

Moving on to step 1:
7 divided by 178 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 178

Advancing to step 2:
The number 178 fits into 75 0 times, leaving a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 178

Advancing to step 3:
178 goes into 751 4 times with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 712 from 751 leaves us with 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 178

On to step 4:
When dividing 390 by 178, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 356 away from 390, we end up with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 178

On to step 5:
When dividing 343 by 178, we get 1 with a remainder of 165.
Use 1 as the next digit of our solution. 
Result so far: 421.0
If we take 178 away from 343, we end up with 165.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 178

Going ahead to step 6:
If we divide 1656 by 178, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 4219.0
Subtracting 1602 from 1656 leaves us with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 178

On to step 7:
540 divided by 178 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 42193.0
Subtracting 534 from 540 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 178

Advancing to step 8:
When dividing 67 by 178, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 421930.0
If we take 0 away from 67, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
The number 178 fits into 670 3 times, leaving a remainder of 136.
Put 3 as the next digit of the answer. 
Result so far: 421930.3
If we take 534 away from 670, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
The number 178 fits into 1360 7 times, leaving a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 421930.37
If we take 1246 away from 1360, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 11:
The number 178 fits into 1140 6 times, leaving a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 421930.376
If we take 1068 away from 1140, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
720 divided by 178 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 421930.3764
Subtract 712 from 720 to 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.

Step 13:
If we divide 80 by 178, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 421930.3764
The remainder is 80 after subtracting 0 from 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 14:
The number 178 fits into 800 4 times, leaving a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 421930.376404
Subtract 712 from 800 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 15:
178 can be fit into 880 4 times, resulting in a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 421930.3764044
If we subtract 712 from 880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 421930.3764044, with a leftover of 1.68e-06.
