74949391 ÷ 198 
We want to divide 74949391 by 198.

Advancing to step 1:
If we divide 7 by 198, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 198

Step 2:
The number 198 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 198

Going ahead to step 3:
198 can be fit into 749 3 times, resulting in a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 594 from 749 leaves us with 155.
Grab the next digit (4) from the dividend, add it to 155, then carry on: 1554 / 198

Going ahead to step 4:
1554 divided by 198 is 7 with a remainder of 168.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtracting 1386 from 1554 leaves us with 168.
Append the next digit (9) from the dividend to 168 and continue with: 1689 / 198

Advancing to step 5:
198 can be fit into 1689 8 times, resulting in a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 378.0
If we take 1584 away from 1689, we end up with 105.
Bring next digit (3) of the dividend behind the 105 and repeat the process: 1053 / 198

Step 6:
198 goes into 1053 5 times with a remainder of 63.
Use 5 as the next digit of our solution. 
Result so far: 3785.0
Subtract 990 from 1053 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 198

Going ahead to step 7:
198 can be fit into 639 3 times, resulting in a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 37853.0
The remainder is 45 after subtracting 594 from 639.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 198

Advancing to step 8:
The number 198 fits into 451 2 times, leaving a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 378532.0
If we take 396 away from 451, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
198 can be fit into 550 2 times, resulting in a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 378532.2
Deduct 396 from 550 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 10:
198 can be fit into 1540 7 times, resulting in a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 378532.27
The remainder is 154 after subtracting 1386 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
198 can be fit into 1540 7 times, resulting in a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 378532.277
Deduct 1386 from 1540 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 378532.277 and a remainder of 0.0154.
