73991878 ÷ 630 
We're looking to find how many times 630 goes into 73991878.

Moving on to step 1:
630 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 630

Moving on to step 2:
The number 630 fits into 73 0 times, leaving a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 630

Moving on to step 3:
If we divide 739 by 630, we get 1 and a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 630 from 739 to get 109.
Include the next digit (9) from the dividend after 109, then repeat: 1099 / 630

Going ahead to step 4:
The number 630 fits into 1099 1 times, leaving a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 630 from 1099, we get 469.
Append the next digit (1) from the dividend to 469 and continue with: 4691 / 630

Step 5:
When dividing 4691 by 630, we get 7 with a remainder of 281.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
The remainder is 281 after subtracting 4410 from 4691.
Bring next digit (8) of the dividend behind the 281 and repeat the process: 2818 / 630

Step 6:
630 can be fit into 2818 4 times, resulting in a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 1174.0
If we subtract 2520 from 2818, we get 298.
Fetch the next digit (7) from the dividend, attach it to 298 and continue: 2987 / 630

On to step 7:
If we divide 2987 by 630, we get 4 and a remainder of 467.
Record the quotient 4 as the next digit in the result. 
Result so far: 11744.0
Subtracting 2520 from 2987 leaves us with 467.
Grab the next digit (8) from the dividend, add it to 467, then carry on: 4678 / 630

Going ahead to step 8:
630 goes into 4678 7 times with a remainder of 268.
Put 7 as the next digit of the answer. 
Result so far: 117447.0
Deduct 4410 from 4678 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 9:
The number 630 fits into 2680 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 117447.4
Subtracting 2520 from 2680 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
When dividing 1600 by 630, we get 2 with a remainder of 340.
The next digit of our result is 2. 
Result so far: 117447.42
Subtract 1260 from 1600 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
630 can be fit into 3400 5 times, resulting in a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 117447.425
Subtracting 3150 from 3400 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
When dividing 2500 by 630, we get 3 with a remainder of 610.
Write down 3 as next digit of the result. 
Result so far: 117447.4253
Subtract 1890 from 2500 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 13:
630 goes into 6100 9 times with a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 117447.42539
Subtract 5670 from 6100 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 14:
630 can be fit into 4300 6 times, resulting in a remainder of 520.
Use 6 as the next digit of our solution. 
Result so far: 117447.425396
The remainder is 520 after subtracting 3780 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 15:
5200 divided by 630 is 8 with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 117447.4253968
If we take 5040 away from 5200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
When dividing 1600 by 630, we get 2 with a remainder of 340.
Use 2 as the next digit of our solution. 
Result so far: 117447.42539682
The remainder is 340 after subtracting 1260 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 117447.42539682, and the remainder is 3.4e-07.
