We look at the division of 76978290 by 189 
Our goal is to divide 76978290 by 189.

Step 1:
If we divide 7 by 189, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 189

Step 2:
76 divided by 189 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 189

Advancing to step 3:
189 can be fit into 769 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 756 from 769 and we're left with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 189

Moving on to step 4:
When dividing 137 by 189, we get 0 with a remainder of 137.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 137 after subtracting 0 from 137.
Bring next digit (8) of the dividend behind the 137 and repeat the process: 1378 / 189

Step 5:
1378 divided by 189 is 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 407.0
Subtract 1323 from 1378 to get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 189

Step 6:
189 can be fit into 552 2 times, resulting in a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 4072.0
Deduct 378 from 552 and we're left with 174.
Grab the next digit (9) from the dividend, add it to 174, then carry on: 1749 / 189

On to step 7:
189 can be fit into 1749 9 times, resulting in a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 40729.0
Deduct 1701 from 1749 and we're left with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 189

Going ahead to step 8:
189 goes into 480 2 times with a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 407292.0
The remainder is 102 after subtracting 378 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
189 can be fit into 1020 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 407292.5
If we take 945 away from 1020, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
189 can be fit into 750 3 times, resulting in a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 407292.53
The remainder is 183 after subtracting 567 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 11:
189 goes into 1830 9 times with a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 407292.539
The remainder is 129 after subtracting 1701 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
If we divide 1290 by 189, we get 6 and a remainder of 156.
The next digit of our result is 6. 
Result so far: 407292.5396
The remainder is 156 after subtracting 1134 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 13:
The number 189 fits into 1560 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 407292.53968
Deduct 1512 from 1560 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
If we divide 480 by 189, we get 2 and a remainder of 102.
The next digit of our result is 2. 
Result so far: 407292.539682
The remainder is 102 after subtracting 378 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
1020 divided by 189 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 407292.5396825
If we subtract 945 from 1020, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
When dividing 750 by 189, we get 3 with a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 407292.53968253
If we take 567 away from 750, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final result is 407292.53968253 with a remainder of 1.83e-07.
