Let's divide 51603988 by 698
Let's see how many times 698 fits into 51603988.

Advancing to step 1:
5 divided by 698 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 698

Step 2:
51 divided by 698 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 698

Let's proceed to step 3:
698 can be fit into 516 0 times, resulting in a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Grab the next digit (0) from the dividend, add it to 516, then carry on: 5160 / 698

Advancing to step 4:
698 can be fit into 5160 7 times, resulting in a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 4886 from 5160, we get 274.
Bring next digit (3) of the dividend behind the 274 and repeat the process: 2743 / 698

On to step 5:
The number 698 fits into 2743 3 times, leaving a remainder of 649.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 2094 from 2743, we get 649.
Append the next digit (9) from the dividend to 649 and continue with: 6499 / 698

Moving on to step 6:
698 goes into 6499 9 times with a remainder of 217.
Use 9 as the next digit of our solution. 
Result so far: 739.0
If we take 6282 away from 6499, we end up with 217.
Grab the next digit (8) from the dividend, add it to 217, then carry on: 2178 / 698

Let's proceed to step 7:
698 goes into 2178 3 times with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 7393.0
Deduct 2094 from 2178 and we're left with 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 698

Moving on to step 8:
When dividing 848 by 698, we get 1 with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 73931.0
Deduct 698 from 848 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
The number 698 fits into 1500 2 times, leaving a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 73931.2
If we subtract 1396 from 1500, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
1040 divided by 698 is 1 with a remainder of 342.
Record the quotient 1 as the next digit in the result. 
Result so far: 73931.21
If we take 698 away from 1040, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 11:
698 can be fit into 3420 4 times, resulting in a remainder of 628.
The next digit of our result is 4. 
Result so far: 73931.214
Subtract 2792 from 3420 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 12:
When dividing 6280 by 698, we get 8 with a remainder of 696.
Write down 8 as next digit of the result. 
Result so far: 73931.2148
Subtract 5584 from 6280 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 13:
The number 698 fits into 6960 9 times, leaving a remainder of 678.
Record the quotient 9 as the next digit in the result. 
Result so far: 73931.21489
Deduct 6282 from 6960 and we're left with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Step 14:
6780 divided by 698 is 9 with a remainder of 498.
The number 9 becomes the next digit in our result. 
Result so far: 73931.214899
If we subtract 6282 from 6780, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

In conclusion, the division gives 73931.214899 with a balance of 4.98e-05.
