We look at the division of 84573290 by 939 
We want to divide 84573290 by 939.

On to step 1:
939 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 939

Going ahead to step 2:
939 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 939

Let's proceed to step 3:
845 divided by 939 is 0 with a remainder of 845.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 845 to get 845.
Append the next digit (7) from the dividend to 845 and continue with: 8457 / 939

Step 4:
939 goes into 8457 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 8451 away from 8457, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 939

On to step 5:
63 divided by 939 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 939

Step 6:
939 goes into 632 0 times with a remainder of 632.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
The remainder is 632 after subtracting 0 from 632.
Include the next digit (9) from the dividend after 632, then repeat: 6329 / 939

Let's proceed to step 7:
If we divide 6329 by 939, we get 6 and a remainder of 695.
Put 6 as the next digit of the answer. 
Result so far: 9006.0
Subtracting 5634 from 6329 leaves us with 695.
Include the next digit (0) from the dividend after 695, then repeat: 6950 / 939

Step 8:
939 can be fit into 6950 7 times, resulting in a remainder of 377.
Use 7 as the next digit of our solution. 
Result so far: 90067.0
Deduct 6573 from 6950 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
939 can be fit into 3770 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 90067.4
If we take 3756 away from 3770, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
When dividing 140 by 939, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 90067.4
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
939 goes into 1400 1 times with a remainder of 461.
The next digit of our result is 1. 
Result so far: 90067.401
Subtract 939 from 1400 to get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Step 12:
When dividing 4610 by 939, we get 4 with a remainder of 854.
The next digit of our result is 4. 
Result so far: 90067.4014
Subtracting 3756 from 4610 leaves us with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Let's proceed to step 13:
If we divide 8540 by 939, we get 9 and a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 90067.40149
If we subtract 8451 from 8540, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 14:
When dividing 890 by 939, we get 0 with a remainder of 890.
Write down 0 as next digit of the result. 
Result so far: 90067.40149
If we subtract 0 from 890, we get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Going ahead to step 15:
If we divide 8900 by 939, we get 9 and a remainder of 449.
The next digit of our result is 9. 
Result so far: 90067.4014909
If we subtract 8451 from 8900, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 16:
When dividing 4490 by 939, we get 4 with a remainder of 734.
Use 4 as the next digit of our solution. 
Result so far: 90067.40149094
If we take 3756 away from 4490, we end up with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

In conclusion, the division gives 90067.40149094 with a balance of 7.34e-07.
