We look at the division of 73485870 by 528 
We want to divide 73485870 by 528.

Step 1:
When dividing 7 by 528, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 528

Moving on to step 2:
The number 528 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 subtract 0 from 73, we get 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 528

On to step 3:
528 goes into 734 1 times with a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 206 after subtracting 528 from 734.
Grab the next digit (8) from the dividend, add it to 206, then carry on: 2068 / 528

Moving on to step 4:
If we divide 2068 by 528, we get 3 and a remainder of 484.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 484 after subtracting 1584 from 2068.
Bring next digit (5) of the dividend behind the 484 and repeat the process: 4845 / 528

Step 5:
528 goes into 4845 9 times with a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 139.0
The remainder is 93 after subtracting 4752 from 4845.
Fetch the next digit (8) from the dividend, attach it to 93 and continue: 938 / 528

Going ahead to step 6:
If we divide 938 by 528, we get 1 and a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 1391.0
If we subtract 528 from 938, we get 410.
Grab the next digit (7) from the dividend, add it to 410, then carry on: 4107 / 528

On to step 7:
If we divide 4107 by 528, we get 7 and a remainder of 411.
Use 7 as the next digit of our solution. 
Result so far: 13917.0
If we take 3696 away from 4107, we end up with 411.
Bring next digit (0) of the dividend behind the 411 and repeat the process: 4110 / 528

On to step 8:
528 can be fit into 4110 7 times, resulting in a remainder of 414.
Record the quotient 7 as the next digit in the result. 
Result so far: 139177.0
If we take 3696 away from 4110, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 9:
528 goes into 4140 7 times with a remainder of 444.
Record the quotient 7 as the next digit in the result. 
Result so far: 139177.7
Subtract 3696 from 4140 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 10:
If we divide 4440 by 528, we get 8 and a remainder of 216.
Put 8 as the next digit of the answer. 
Result so far: 139177.78
The remainder is 216 after subtracting 4224 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
When dividing 2160 by 528, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 139177.784
Subtracting 2112 from 2160 leaves us 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.

Let's proceed to step 12:
528 goes into 480 0 times with a remainder of 480.
The next digit of our result is 0. 
Result so far: 139177.784
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
If we divide 4800 by 528, we get 9 and a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 139177.78409
Subtract 4752 from 4800 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 528, we get 0 and a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 139177.78409
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 15:
528 can be fit into 4800 9 times, resulting in a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 139177.7840909
The remainder is 48 after subtracting 4752 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
The number 528 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 139177.7840909
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 139177.7840909 with a remainder of 4.8e-07.
