We look at the division of 73198474 by 186 
Our goal is to divide 73198474 by 186.

Going ahead to step 1:
186 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 186

Advancing to step 2:
The number 186 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 186

Advancing to step 3:
186 goes into 731 3 times with a remainder of 173.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 173 after subtracting 558 from 731.
Take the next digit (9) from the dividend and append it to 173, then repeat: 1739 / 186

Moving on to step 4:
186 can be fit into 1739 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 1674 from 1739 leaves us with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 186

Advancing to step 5:
186 goes into 658 3 times with a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 393.0
If we subtract 558 from 658, we get 100.
Grab the next digit (4) from the dividend, add it to 100, then carry on: 1004 / 186

On to step 6:
When dividing 1004 by 186, we get 5 with a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 3935.0
Subtracting 930 from 1004 leaves us with 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 186

On to step 7:
186 goes into 747 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 39354.0
If we subtract 744 from 747, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 186

Advancing to step 8:
When dividing 34 by 186, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 393540.0
The remainder is 34 after subtracting 0 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
If we divide 340 by 186, we get 1 and a remainder of 154.
Put 1 as the next digit of the answer. 
Result so far: 393540.1
The remainder is 154 after subtracting 186 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 10:
186 can be fit into 1540 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 393540.18
If we take 1488 away from 1540, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
When dividing 520 by 186, we get 2 with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 393540.182
Subtracting 372 from 520 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 12:
186 can be fit into 1480 7 times, resulting in a remainder of 178.
The next digit of our result is 7. 
Result so far: 393540.1827
Subtract 1302 from 1480 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 13:
1780 divided by 186 is 9 with a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 393540.18279
Subtracting 1674 from 1780 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 14:
If we divide 1060 by 186, we get 5 and a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 393540.182795
The remainder is 130 after subtracting 930 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 15:
When dividing 1300 by 186, we get 6 with a remainder of 184.
The next digit of our result is 6. 
Result so far: 393540.1827956
If we take 1116 away from 1300, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
186 can be fit into 1840 9 times, resulting in a remainder of 166.
The next digit of our result is 9. 
Result so far: 393540.18279569
If we subtract 1674 from 1840, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

In conclusion, the division gives 393540.18279569 with a balance of 1.66e-07.
